1、Electrolytic capacitor: the metal foil is the positive electrode (aluminum or tantalum), the oxide film (aluminum oxide or tantalum pentoxide) which is close to the positive electrode is the dielectric, the cathode is composed of conduct...

When buying capacitors, you need to pay attention to not only the choice of brand, not only the choice of capacitor type. More than that, you should pay attention to the capacitor parameters, only to meet the capacitor parameters to meet the...

Electrolytic capacitors are used a lot in electrical equipment, and due to the uneven quality of electrolytic capacitors on the market, the phenomenon of capacitor failure has often occurred. Electrolytic capacitor damage has the following p...

The basic unit of capacitor is Farad (F), however, this unit is too large and rarely used in the field labeling. ??Other unit relationships are as follows. ??1F=1000mF ??1mF=1000μF ??1μF = 1000nF ??1nF = 1000pF ??T...

Snap-in aluminum electrolytic capacitor is a kind of aluminum electrolytic capacitor, the shape is generally cylindrical, compared to the radial-lead type aluminum electrolytic capacitor maybe less people have contacted, but in fact its appl...

Many people will have doubts, how long can aluminum electrolytic capacitors be stored? The most conventional capacitor service life of ShiCaXon capacitors produced by Guangdong Wangxing Electronic Technology Co., Ltd. is 2000 hours, which is...

Capacitors are divided into polarized capacitors and non-polarized capacitors. Generally, porcelain chip capacitors, monolithic capacitors and polyester capacitors are non-polarized capacitors, and non-polarized capacitors do not need to co...

Many manufacturers doing switching power supplies, most of them choose high frequency electrolytic capacitors when purchasing capacitors, do you know the principle? In the power supply circuit, capacitors are often used to pass through the A...

1、Capacity and volume As most electrolytic capacitors are wound, it is easy to expand the volume, so the capacity per unit volume is very large, several times to dozens of times larger than other capacitors. However, the large capacity is...

n the practical application of electrolytic capacitors, sometimes the aluminum electrolytic capacitors inserted on the board will bulge or even explode. When this happens, many manufacturers will directly find the capacitor supplier and susp...
