chip resistor (Surface Mount Resistors) and Color Ring Resistors (Through Hole Resistors) are two common 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 resistor Some considerations between color ring resistance and sound quality: 1 Noise:- chip resistor ： chip resistor Generally, they have 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, chip resistor The structural design can also reduce noise. Therefore, chip resistor It is generally possible to provide a lower noise level in audio devices- Color ring resistance: the structure of color ring resistance 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 chip resistor Color ring resistance may produce high noise level to some extent. 2. Temperature coefficient:- chip resistor ： chip resistor It 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: the temperature coefficient of color ring resistance 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:- chip resistor ： chip resistor It 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: the frequency response of color ring resistance 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

In order to improve the measurement accuracy, the measuring range should be selected according to the nominal value of the measured resistance. Due to the non-linear relationship of the ohmic scale, the middle section of the scale has a fine graduation, so the pointer indicating value should fall as far as possible to the middle section of the scale, that is, within 20%~80% radians from the beginning of the full scale, so as to make the measurement more accurate. Depending on the resistance error level. ± 5%, ± 10% or ± 20% are allowed between the reading and the nominal resistance

The product has started mass production with a monthly output of 3 million (sample price: 20 yen). The place of production is ROHM Electronics Philippines Inc. (Philippines). In the automotive field, with the development of electronization, the number of electronic parts required is increasing. At the same time, the requirements for miniaturization of automotive electronic parts are also increasing. In particular, the requirements for ultra low resistance values for high reliability current detection applicable to electric power steering are also increasing. On the other hand, different from small current mobile machines, the current detection resistor used to control tens of amperes of large current uses 6432 (2512) and other large sizes. The expansion or contraction of such large chip parts under repeated heat may cause damage to solder, so there will be many problems when used in extreme environments with large temperature difference or high humidity. For the PML series developed by Rom this time, the expansion coefficient of the chip itself is close to the glass epoxy resin substrate widely used as the mounting substrate, thus reducing the solder damage caused by heat. In addition, the electrode is set on the long side, which can not only expand the contact area with the substrate, but also reduce the thermal impact of the reduction of the distance between the electrodes, so as to achieve more stable connectivity. Moreover, Rom's original "simplified structure" and long side electrode ensure the smoothness of the heat release path, which makes it possible to achieve the rated power of 3W and ultra-low resistance value of 0.5m Ω required by power steering. In addition, compared with the previous products with the same characteristics, the package area is significantly reduced (about 50%).

SMD components have the advantages of small size, light weight, high installation density, strong seismic resistance, strong anti-interference ability, good high-frequency characteristics, etc. They are widely used in computers, mobile phones, electronic dictionaries, medical electronic products, video recorders, electronic watt hour meters, VCD machines, etc. According to its shape, SMD components can be divided into three categories: rectangular, cylindrical and profiled. There are resistors, capacitors, inductors, transistors and small integrated circuits by type. The nominal method of SMD components is different from that of general components. The following is mainly about the nominal value method of chip resistors. The resistance value of the chip resistor is the same as that of the general resistor, which is marked on the resistor body. There are three methods of nominal resistance value, but the nominal method is not exactly the same as that of the general resistor. 1. Digital cable position nominal method (generally used for rectangular sheet resistance) The digital cable position nominal method is to mark the resistance value with three digits on the resistance body. Its first and second digits are significant digits, and the third digit represents the number of "0" added after the significant digits. This digit will not contain letters. For example, "472 '" means "4700 Ω"; "151" means "1500". If it is a decimal point, use "R" to represent "decimal point", and occupy one significant digit, and the other two are significant digits. For example, "2R4" means "2.4 Ω"; "R15" means "0.15 Ω". 2. Color ring nominal method (generally used for cylindrical fixed resistors) chip resistor Like general resistance, four rings (sometimes three rings) are used to indicate the resistance value. The first ring and the second ring are significant figures, and the third ring is magnification (color ring code is shown in Table 1). For example, "brown, green and black" means "15 Ω"; "blue, gray, orange and silver" means "68k Ω" error ± 10%. 3. E96 digital code and parent mixed nominal method The mixed number code and letter nominal method also uses three digits to indicate the resistance value, that is, "two digits plus one letter", where two digits represent the E96 series resistance code. See Table 2 for details. The third digit is the multiplication rate expressed by letter code (as shown in Table 3). For example, "51D" means "332x103; 332k Ω"; "249Y" means“
