  • Some problems should be paid attention to when using safety capacitor

    Safety capacitance refers to the situation where the capacitor will not cause electric shock and endanger personal safety after failure. It includes X capacitance and Y capacitance. X capacitance is the capacitance that spans between two lines (L-N) of the power line, and metal film capacitance is generally selected; Y capacitance is the capacitance that spans between two lines of power line and ground (L-E, N-E), usually in pairs. Based on the limit of leakage current, the value of Y capacitance should not be too large. Generally, X capacitance is uF and Y capacitance is nF. X-capacitance suppresses differential mode interference, and Y-capacitance suppresses common mode interference. Safety grade of safety capacitor Application of safety grade of safety capacitor

  • Advantages and disadvantages of super capacitor compared with ordinary capacitor, battery and its application

    Electric double layer capacitor, gold capacitor and farad capacitor are just the names of super capacitor. Supercapacitor is an electrochemical physical part, but it does not carry out chemical reaction. Its storage capacity is particularly large, reaching Farad level capacitance. How to increase the area of the two plates? The supercapacitor stores energy by injecting electrolyte. Under the action of the electrode, the electrode surface charge will attract the opposite ions in the surrounding electrolyte solution, making these ions attach to the electrode surface to form a double charge layer, forming a double electric layer capacitor. Because the distance between the two charge layers is very small (generally less than 0.5mm), and the special electrode structure is adopted,

  • Introduction to bypass capacitor: tantalum capacitor, ceramic capacitor, aluminum capacitor

    "In the voltage regulator, tantalum capacitors, multilayer ceramic capacitors, and aluminum electrolytic capacitors are often seen as voltage input and output bypass. Here is a brief introduction. The traditional aluminum electrolytic capacitors of aluminum electrolytic capacitors tend to be large in size, high in ESR and ESL, relatively high in leakage current, and limited in service life (in thousands of hours). OS-CON capacitor uses organic semiconductor electrolyte and aluminum foil cathode to achieve low ESR. Although related to solid polymer tantalum capacitors, these capacitors are actually 10 years or more earlier than tantalum capacitors. Since there is no liquid

  • Basic requirements of bypass and coupling circuits for selection of tantalum capacitors

    "We need to select the tantalum capacitor type according to different circuit requirements. We talked about the basic requirements of power filter circuit for tantalum capacitor type selection before. Now we will talk about the basic requirements of bypass and coupling circuit for tantalum capacitor type selection, hoping to help you. 1. Bypass bypass is a major application of capacitors in circuits. Especially with the increase of the actual density of components on printed boards and the widespread use of large-scale integrated circuits and high-speed circuits, the current mutation will become more serious when the circuit is working, and the noise voltage generated will also be greater. In order to effectively suppress this power line

  • Failure analysis of tantalum chip capacitors

    "The explosion of SMD tantalum capacitors has always been a headache for R&D personnel. Especially in the switching power supply industry, some R&D personnel dare not use SMD tantalum capacitors in circuit design. In fact, as long as we understand the characteristics of the chip tantalum capacitor, we can analyze the reasons for the explosion of the chip tantalum capacitor. Some conclusions are as follows: 1. When designing the power supply of the electronic machine, some of our R&D personnel will use capacitors in parallel on such circuits, On the one hand, the chip tantalum capacitor needs to filter the input signal, on the other hand, it needs to filter according to a certain frequency and power

  • Semiconductor innovation is shaping the future of science and technology

    In today's fast-paced digital era, semiconductor technology is the pillar of innovation, promoting the development of electronic manufacturing. From the unremitting pursuit of smaller and more powerful processors to the breakthrough progress of connectivity and computing paradigm, the semiconductor industry has constantly broken through the possible boundaries. The following are semiconductor technologies that are revolutionizing electronic manufacturing: the transition from 3nm process mass production to 3nm process technology marks an important milestone in semiconductor manufacturing. When the transistor size is reduced to 3 nm, more transistors can be integrated on the same chip area, thus improving the density of transistors. This increase in density means that chips can

  • How to judge the positive and negative poles of tantalum capacitor

    Loose fill technology for your analysis: how to judge the positive and negative poles of tantalum capacitors? Generally speaking, the positive and negative poles of the point capacitor are marked with horizontal lines on the tantalum capacitor, and the side with horizontal lines is the positive pole of the tantalum capacitor, otherwise it is the negative pole. If there is no mark, the short leg side of the tantalum capacitor is the negative pole, and the long leg side is the positive pole. If the positive and negative connection of the tantalum capacitor is reversed, the tantalum capacitor will fail. It is particularly important to judge the positive and negative poles of tantalum capacitors. For this reason, loose fill technology, a manufacturer of tantalum capacitors, has specially made the following figure for major users to judge the positive and negative poles of tantalum capacitors.
