Varistors are already indispensable electronic components in life. They are mainly used to clamp voltage when the circuit is under overvoltage, and absorb excess current to protect sensitive devices. A varistor is a component with transient voltage suppression that can be used in place of a combina

Some friends have suggested that the withstand voltage indicated by the ceramic capacitor refers to the DC voltage. Is the capacitor useful for DC? Is the ceramic dielectric capacitor not a component that works in an AC circuit? This article is to explain the reasons for this issue, I hope that the

High-voltage ceramic capacitors are also a common electronic component in life for high-stability oscillation circuits. In the use we will encounter a lot of problems, this article from the small series to summarize some common problems, together to understand it! 1) What is the role of high voltage

The schematic diagram of the power amplifier input capacitor is written on a polyester capacitor. Can it be replaced by a ceramic capacitor? Yes, but with high voltage resistance, the high frequency performance of high voltage ceramic capacitors is better than polyester capacitors. No matter what ca

The ceramic capacitor is a capacitor made of a ceramic material as a medium, a metal film coated on the surface of the ceramic, and then sintered at a high temperature as an electrode. It is commonly used in high-stability oscillator circuits as loops, bypass capacitors, and pad capacitors. The cera

The ceramic capacitor is a capacitor made of a ceramic material as a medium, coated with a metal film on the surface of the ceramic, and then sintered at a high temperature as an electrode. It is usually used in a high-stability oscillation circuit as a loop, a bypass capacitor, and Pad capacitors.

High-voltage ceramic capacitors are high-voltage ceramic capacitors used in power systems. Generally, high-voltage ceramic capacitors are used in power metering, energy storage, and voltage division. High-voltage ceramic capacitors have been widely used and not in the LED lamp industry. High-voltage

A regular computer power supply manufacturer must have a rectifier bridge, a main control module, a main capacitor, a transformer, various MOS tubes, etc. Among them, the EMI module contains X capacitors and Y capacitors. Why are there safety regulations X and Y on the power supply? What about capac

High-voltage capacitors generally refer to capacitors above 1kv or capacitors above 10kv. The main advantage of high-voltage capacitors is that they are small in size, high in withstand voltage, and stable in performance. So what is the high-voltage capacitor over-power capability? What is the misun

The question that everyone has been discussing all the time, what is the life of the capacitor? When the varistor is normally shipped, the age of the varistor will be related to improper operation. Therefore, in order to protect the life of the varistor, everyone should use it normally. The characte
