Nine advantages of film capacitors

The development prospects of film capacitors are considerable, and the number of film capacitors used is increasing. What are the advantages of film capacitors?

Film capacitors have become a market trend to replace electrolytic capacitors. Metallized film capacitors have made considerable progress. The volume and weight of capacitors have been reduced by 3 to 4 times. The technology has also undergone great changes. Many advantages of film capacitors have made film capacitors in DC It is a trend to replace electrolytic capacitors in filtering.

Nine advantages of film capacitors:

①The ability to withstand high current.

②Strong anti-surge ability.

③It can withstand the 2.5KV peak voltage with the pulse width rising edge and falling edge ratio of 1.2μs:50μs or 8μs:20μs.

④ Ability to withstand high peak current, small inductance, and fast charge and discharge speed.

⑤High withstand voltage, able to withstand overvoltage 1.5 to the rated voltage.

⑥No polarity, can withstand reverse pulse voltage for a long time.

⑦The dielectric loss is small, the temperature characteristic is good, and it can work for a long time at 120℃.

⑧Small size, long life, no acid pollution.

⑨ Can be stored for a long time.
