Color ring resistance (Also known as code resistor or resistor) is an electronic component with colored bands, which is used to represent the value of resistance. It usually consists of a thin resistor and several colored rings. Each color band represents a number or a multiplication factor. The resistance value of DMMT3906W-7-F can be determined by reading the color of these color bands. In general, Color ring resistance There are four or five colored bands, each representing a value or a multiplication factor. The order of these colored bands is from left to right, usually starting with a metal band. The following are common Color ring resistance Color band of and corresponding value: 1 The first ring band is the first digit, representing the highest position of the resistance value. 2. The second ring band is the second digit, representing the secondary high order of the resistance value. 3. The third ring band is the multiplication factor, representing the order of magnitude of the resistance value. 4. The fourth ring band is the tolerance value, indicating the allowable error range of the resistance value. Sometimes there is a fifth band, which represents the temperature coefficient. read Color ring resistance The following steps should be followed: 1 Determine the order of color bands: usually from left to right, the first digit, the second digit, the multiplication factor, and the tolerance value. 2. Identify the color of each color band: each color represents a numerical value or multiplication factor. have access to Color ring resistance Color coding table to accurately identify. 3. Calculate the resistance value: according to the value or multiplication factor represented by each ring band, calculate the final resistance value according to a certain combination of rules. 4. Determine the tolerance range: determine the allowable error range of the resistance value according to the color of the tolerance band. 5. If there is a fifth ring band, it represents the temperature coefficient, and the change rate of resistance value with temperature can be determined according to the color. Note that when reading Color ring resistance The order and color between the colored bands should be carefully distinguished. Correct identification and calculation of the value of each ring can accurately determine Color ring resistance Resistance.

Surface Mount Resistors and Color ring resistance (Through Hole Resistors) are two commonly used resistance devices, which play the roles of current limiting, voltage dividing, protection, etc. in electronic circuits. For audio equipment, the selection of resistance devices is very important to the sound quality. The following is about chip resistance and Color ring resistance Some considerations with sound quality: 1 Noise: - SMD resistor: SMD resistor usually has smaller size and weight, which enables them to better resist mechanical and CY7C263-20WC thermal stress and reduce the generation of internal noise. In addition, the structure design of SMD resistor can also reduce noise. Therefore, SMD resistors can generally provide a lower noise level in audio equipment- Color ring resistance ： Color ring resistance Its structure is relatively large, and there are many internal contacts and welding points, which may lead to some current noise and thermal noise. Therefore, relative to the chip resistance, Color ring resistance To some extent, it may produce high noise levels. 2. Temperature coefficient: - SMD resistance: SMD resistance usually has a small temperature coefficient, which means that its resistance value changes little when the temperature changes. This is important for audio devices because they need to maintain stable operating conditions to avoid distortion of sound quality- Color ring resistance ： Color ring resistance The temperature coefficient of is relatively large, which means that its resistance value may change greatly when the temperature changes. This may have a certain impact on the working conditions of audio equipment, which may lead to changes in sound quality. 3. Frequency response: - SMD resistance: SMD resistance usually has a high frequency response and can provide uniform impedance characteristics in a wider frequency range. This is important for audio devices because they need to transmit broadband audio signals without introducing additional distortion- Color ring resistance ： Color ring resistance The frequency response of is relatively low, which may introduce additional inductance and capacitance effects at higher frequencies, resulting in distortion of audio signals. It should be noted that in addition to the characteristics of the resistance device itself, the resistance value, accuracy and power capacity of the resistance will also affect the sound quality

Color ring resistance , also known as "resistance" in electronic and electrical components, is a passive component with a specific resistance value. It represents the resistance value and tolerance value through the color coded ring belt, and is often used to adjust the current and voltage in the circuit to achieve the adjustment of circuit performance. 1. Composition: Color ring resistance It is composed of CLC432AJE inner core, insulation layer, color ring (ribbon), package, etc. The inner core is a resistance material made of carbon, metal or other materials. The insulation layer is used to prevent the impact of its external environment on the resistance material. The color ring represents the resistance value and tolerance value according to certain coding rules. 2. Features: Color ring resistance The utility model has the advantages of simple structure, stability, reliability, low price, high precision, high temperature resistance, etc. Because the color coding makes it intuitive and easy to read, it is easy to identify and distinguish the resistance with different values. 3. Power: Color ring resistance The power of depends on its size, resistance value and working environment. Generally, the power is 1/8W, 1/4W, 1/2W, etc., which shall be selected according to specific requirements. 4. Packaging: Color ring resistance Common packaging forms include in-line, SMD, etc. Different packaging forms are suitable for different applications.

Through correct selection and use, the performance and stability of the circuit can be improved.

At present, domestic or imported TV sets and radio recorders are widely used Color ring resistance Its advantage is that in the process of assembly, debugging and repair, the color ring can be seen from any angle and the resistance value can be read without moving the element, which is very convenient to use. It has been introduced in magazines in the past Color ring resistance Reading method: when reading according to the method, conversion is required, which is troublesome. Here is a method to quickly identify the resistance value. The first and second rings with four color rings respectively represent the first two digits of the resistance value; The third ring represents magnification; The fourth ring represents error. The key to fast identification is to determine the resistance value within a certain order of magnitude according to the color of the third ring, such as the number of K points or tens of K points, and then put the number of generations read out of the first two rings into it, so that the number can be read out quickly. Here are some key points to master this method: (1) Remember the number represented by each color of the first and second rings. It can be remembered as follows: brown 1, red 2, orange 3, yellow 4, green 5, blue 6, purple 7, gray 8, white 9, black 0. In this way, read together and repeat several times to remember. The key to quick recognition is to remember the resistance range represented by the third ring color accurately. Specifically, gold: a few dots, black: several tens of Ω, brown: hundreds of dozens of Ω, red: a few dots, k Ω, orange: a few tens of k Ω, yellow: hundreds of dozens of k Ω, green: a few dots, M Ω, blue: a few tens of M Ω From the perspective of order of magnitude, they can be divided into three major levels in the body, namely, gold, black, and brown are ohmic; Red, orange and yellow are at the thousand euro level; Green and blue are megaohmic. This division is for the convenience of memory. (2) When the second ring is black, the color of the third ring represents an integer, that is, several, dozens, hundreds of k Ω, etc. This is a special case when reading. Pay attention. For example, if the third ring is red, its resistance is the whole number of k Ω. (3) Remember the error represented by the fourth ring color, that is, gold is 5%, silver is 10%, colorless is 20%. The following is an example: Example 1. When the four color rings are yellow, orange, red and gold in sequence, because the third ring is red and the resistance range is several k Ω, the reading is 43k Ω if the numbers "4" and "3" represented by yellow and orange are substituted.

Color ring resistance It is an EM78P153SNJ resistor that uses color coding to indicate its resistance value, tolerance and sometimes temperature coefficient. This coding method is convenient for fast and intuitive identification of resistance characteristics, especially when space is limited or it is not convenient to print numbers. Color ring resistance Usually, the resistor insulator is painted with rings of different colors to represent different values. Color ring resistance The identification method of is usually based on standard color coding. The following is how to correctly identify Color ring resistance Steps of: 1 Understand the color code: each color represents a specific number. The following is the standard color code table: ● Black: 0 ● Brown: 1 ● Red: 2 ● Orange: 3 ● Yellow: 4 ● Green: 5 ● Blue: 6 ● Purple (or violet): 7 ● Gray: 8 ● White: 92 Number of color rings to identify resistance: common Color ring resistance There are four rings, five rings and six rings. Different ring numbers represent different information: ● Four ring resistor: the first two rings represent the first two digits of the resistance value, the third ring is the multiplier, and the fourth ring is the tolerance. ● 5-loop resistor: the first three loops represent the first three digits of the resistance value, the fourth loop is the multiplier, and the fifth loop is the tolerance. ● 6-loop resistor: the first three loops are the same as the 5-loop resistor, the fourth loop is the multiplier, the fifth loop is the tolerance, and the sixth loop represents the temperature coefficient. 3. Read resistance value and multiplier: The first two or three color rings (depending on the number of rings of the resistor) correspond to a number respectively, and these numbers together are the basic digital part of the resistance value. The next color ring (multiplier) tells us to multiply this number by the power of 10. 4. Read the tolerance: The tolerance color ring indicates the possible deviation range of the nominal resistance value of the resistor. For example, gold represents ± 5%, silver represents ± 10%, and no color ring represents ± 20%. 5. Read the temperature coefficient (if any): on the 6-ring resistor, the last color ring shows the resistance changes with temperature, expressed in ppm/° C (degrees Celsius per millionth). The following are some examples to illustrate how to read the color ring electrovalve: ● Example 1 (4-ring resistor): brown, black, red, gold. This means that the resistance value is 1 (brown) 0 (black) x 100 (red

The resistance values and errors of carbon resistors and some 1/8 watt carbon film resistors are represented by color rings. There are three or four color rings on the resistance. The first color ring is near the resistance end, and the second, third, and fourth color rings are in order, as shown in the figure below. The first color ring represents the largest digit of the resistance value, the second color ring represents the second digit, and the third color ring represents that the resistance value should not have several zeros. The fourth color ring indicates the resistance error. Domestic or imported TV sets and radio recorders are widely used Color ring resistance Its advantage is that in the process of assembly, debugging and repair, the color ring can be seen from any angle and the resistance value can be read without moving the element, which is very convenient to use.

For example, the three rings are red, orange and yellow, and the correct reading is 230000 ohms. If the ring is yellow, orange and red, it is 4300 ohms. For those who are not familiar with the color ring, it is recommended to identify it with a multimeter.

The gold ring indicates that the error is 5%. Example 2 When the four color rings are brown, black, orange and gold in sequence, because the third ring is orange and the second ring is black, the resistance value should be tens of k Ω, and the number "1" represented by brown is substituted, and the reading is 10k Ω. The fourth ring is gold, with an error of 5% In some cases where it is difficult to distinguish, you can also compare the colors of the two starting ends, because the first color of the calculation starting part is not gold, silver, and black. If these three colors are near the edge, it needs to be calculated in reverse. Color ring resistance There are two ways to mark the color of. Zone of both
