1) The internal fault of electrolytic capacitor is short circuit and open circuit. The fault phenomenon is burning switch tube and other current limiting components, such as the current limiting resistor in the insurance and switching power supply. A filter capacitor in high voltage and high current

Ceramic chip capacitance (ceramic capacitor) is a kind of capacitor which is made of ceramic material, coated with a metal film on the ceramic surface and then sintered at high temperature as an electrode. Ceramic chip capacitors are often used as circuit capacitors and pad capacitors in high stabil

6. Long storage capacitors: adding rated DC voltage for a long time before use actually has little effect on the capacitance and loss of capacitors, however, it will increase the leakage current of the capacitors and reduce the voltage. For long storage capacitor treatment, DC voltage should be grad

1. DC electrolytic capacitors are polar: the polarity of the capacitor is marked on the base of the capacitor so as not to cause circuit short-circuit or capacitor damage due to polarity. Use bipolar electrolytic capacitors when using non-stationary polarity or on uncertain circuits. Note that DC el

When it comes to CBB capacitors, there may be some strange, but when it comes to electrolytic capacitors, most people are familiar. Electrolytic capacitors are widely used and used as one of the mainstream capacitors, but they are gradually replaced by CBB capacitors. So why do CBB capacitors gradua

4. Leakage current. The dielectric of the capacitor has a great hindrance to the DC current. However, because the electrolyte is immersed in the aluminum oxide film medium, a very small current called leakage current is produced when applied the voltage and when the oxide film is regenerated and rep

1. Capacitance value. The capacitance of an electrolytic capacitor depends on the impedance it presents when it works at an AC voltage. Therefore, the value of the AC capacitance varies with the operating frequency, voltage, and measurement method. Standard JISC 5102 states that the capacitance of a

Because the working temperature of the capacitor is increased by 10 ℃ and the service life is halved, so don't think that the aluminum electrolytic capacitor with 2000 hours life is better than 1000 hours, we should pay attention to the test temperature of confirming the lifetime. Each manufacturer

Bolt type aluminum electrolytic capacitor is named after bolt because its pin is bolt. It has the characteristics of high voltage, large capacity, high withstand current and so on. Bolted electrolytic capacitors are: CD92: low voltage, large capacity, low loss, low leakage, small volume, high rippl
