Qing Quan electronic 400v2200uf electrolytic capacitors electrolytic capacitors

Qing Quan Electronics has advanced the development of equipment and testing equipment, in accordance with the relevant national standards for our product formulations strict, comprehensive and realistic testing, and the use of internal control standards higher than international companies, fully ensure the high reliability of products we offer sex. This is an era of knowledge economy, science and technology is productivity, we will continue to high standards to itself and take advantage of deep expertise and experience, to create a starting point of the elite high-tech enterprises. Qing Quan Electronics - aluminum electrolytic capacitor R & D and production experts! Capacitance of the application of electronic circuits, only in the capacitor charging process, current flows through only after the end of the charging process, the capacitor can not pass DC, acts as a "DC blocking" role in the circuit. Circuits, capacitors are often used as coupling, bypass, filtering, etc., are using it, "through exchanges, DC blocking" features. Small-capacity capacitor, typically used in high-frequency circuits, such as radios, transmitters and oscillators. Large-capacity capacitor is often used for filtering and storage charges. But also a feature, usually more than 1μF capacitors are electrolytic capacitors, aluminum electrolytic capacitors there, filled with electrolyte, and leads to two electrodes, as a positive (+) and negative (-) terminals, and other capacitors different They polarity in the circuit can not be wrong, and the other capacitors are not polar.
