DC support capacitor

DC support capacitor, also known as DC-Link capacitor. DC support capacitor belongs to one kind of passive devices. DC support capacitors mainly use polypropylene film dielectric DC support capacitors, which have the advantages of high voltage resistance, high current resistance, low impedance, low inductance, small capacity loss, small leakage current, good temperature performance, fast charging and discharging speed, long service life (about 100,000 hours), good safety, explosion-proof stability, and convenient installation without polarity. It is widely used in power electronics industry.
