1.Foreword Filter capacitor plays an important role in the rectifier filter circuit, the larger the capacitance, the better the filtering effect. Especially in the low-voltage rectifier (such as 5V, 3.3V or lower voltage) output, because the filter capacitor capacity is not large enough to prod

As a new type of energy storage device, super capacitor has super storage capacity. In the mechanism of energy storage, it is highly reversible, has a long life, can repeatedly impulse and discharge thousands of times, and has a very large current, in addition, it has a wide range of voltage and

Supercapacitors are also called supercapacitors, gold capacitors, gold capacitors, energy storage capacitors, Farah capacitors, electrochemical capacitors or double layer capacitors (EDLC, or Electric Double Layer capacitors), which store electricity by polarization electrolytes. A new type of

In general, varistors are often used in parallel with protected devices or devices, and under normal circumstances the DC or AC voltages at both ends of the varistors should be lower than the nominal voltage, even in the worst case of power fluctuations. Nor should it be higher than the maximum con

The voltage protection effect of a varistor in an electronic circuit, usually allows electric shock with a current fuse or additional overvoltage protection. Working principle of varistor: voltage and current intensity of varistor identify special nonlinear relation. When the voltage applied on both

Some characteristics of thin film capacitors include non-polarity, good performance, high working frequency, and low material loss. And the thin film capacitor product is smaller, the same working rate of the capacitance, the film capacitance shape than the electrolytic capacitance volume is half. H

4)Oil leakageReasons: improper handling, the porcelain casing and shell contact place cracks or porcelain casing cracks, bruising; Improper installation, screw tightening, the force is too fierce, resulting in welding damage; There are cracks in the quality of the components. After putting into use,

1)Explosion, fuel injectionMost occurs in a high voltage capacitor bank that does not have an internal protection element due to an interphase short circuit or breakdown of the relative shell.An internal protective element can be installed to remove the capacitor from the power network before explos

Voltage, temperature, capacity and equivalent resistance are several important parameters of capacitance, and the lower the ESR is, the better its quality is. ESR is related to capacitance, frequency, voltage, temperature and so on.When the voltage is fixed, the larger the capacity, the lower the ES

The two metal phrases with close shells separated by materials the in the center, is a capacitor. The two electrodes are made up of active substances and electrics maintained for electrification, which are called polar plates. What's in the center is his carrier. Capacitors are also divided into fix
