Aluminum electrolytic capacitors are made of aluminum cylinders as negative poles, which are filled with liquid electrolyte, and a curved aluminum strip is inserted as positive poles. Common sense of the use of aluminum electrolytic capacitors includes the following points: 1. The DC electrolytic capacitor can only be used on a DC circuit, and its polarity [...]
Supercapacitors refers to a new type of energy storage device between traditional capacitors and rechargeable batteries. It not only has the characteristics of rapid charge and discharge of capacitors, but also has the energy storage characteristics of batteries. The supercapacitor is a new type of component that stores energy through the interface double layer formed between [...]
The use of film capacitors is very wide, such as air conditioners, refrigerators, washing machines, fans, power supplies and so on. Film capacitors are also involved in the transportation industry, and the familiar electric cars also have film capacitors. Application in power electronic circuits. Film capacitor are used here, mainly to play a role in buffering [...]
Investigate the secret of "longevity" of aluminum electrolytic capacitors In order to prevent global warming, LED lighting (Light Emitting Diode) as a means of saving energy has attracted attention. LED has been applied and developed in many fields, especially to prevent global warming caused by lighting products, CO2 reduction, energy saving and other means, LED will [...]
High-frequency low-impedance refers to the ability of the capacitor to withstand ripple current and its small internal resistance. Compared with ordinary, the product itself is not easy to heat in the circuit and cause premature failure. In particular, because of its miniaturization, light weight and high efficiency, switching power supply modules require small and large electrolytic [...]
