Film capacitor power(I)

The film capacitor has many excellent characteristics, non-polarity, high insulation resistance, excellent frequency characteristics (wide frequency response), and small dielectric loss. Therefore, a thin film capacitor is used in a large amount in an analog circuit.

What the editor wants to tell you today is about the energization of the film capacitor. The current operation of the film capacitor is very regular. When using a film capacitor, we will find that the current is not normal. How do we handle this? The problem is.

Film capacitors are manufactured and polarized similarly to the methods used to make aluminum electrolytic capacitors, however, their storage time is not limited and they can operate for long periods of time without DC polarity. Instantaneous reverse voltage does not generally damage capacitors, but aluminum electrolytic capacitors are different.
