Feature
1. Metal case package, Sealed with resin;
2. High voltage power system application;
3. High power circuit;
4. Resistance to high voltage, with self-healing;
5. High ripple current, high dv / dt withstand capability.
Function
In the output filter of a DC power supply, the job of the capacitor is to maintain a constant DC value by removing as much power ripple as possible.
All AC-DC converters, whether they are linear supplies or have some kind of switching element to them, require a mechanism to take the varying power on the AC side and produce a constant power on the DC side.
