The development prospects of film capacitors are considerable, and the number of film capacitors used by everyone is increasing. Why can film capacitors win everyone's praise? Related to its advantages.
It has become a market trend for film capacitors to replace electrolytic capacitors. Metallized film capacitors have made great progress. The volume and weight of capacitors have been reduced by 3 to 4 times. The technology has also changed a lot. Film capacitors have many advantages, and film capacitors are used in DC filtering. The trend of replacing electrolytic capacitors.
9 advantages of film capacitors:
①The ability to withstand high currents.
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 currents, small inductance, and fast charging and discharging.
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.
⑨Can be stored for a long time.
