The development prospects of film capacitors are considerable, and the number of film capacitors used by people has been increasing online in the past few years. Why film capacitors win everyone's praise is inseparable from its advantages. This article tells you about the nine advantages of film capacitors! Let’s learn together!
Film capacitors have become a market trend instead of electrolytic capacitors, and metallized film capacitors have made great progress.The volume and weight of capacitors have been reduced by 3 to 4 times, and technology has also changed a lot, giving film capacitors many advantages. It is a trend for film capacitors to replace electrolytic capacitors in DC filtering.
Nine major advantages of film capacitors:
①Ability to withstand high current.
② Strong surge resistance.
③Can withstand a 2.5KV spike voltage with a 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 charging and discharging speed.
⑤ High voltage resistance, able to withstand an overvoltage of 1.5% higher than the rated voltage.
⑥No polarity, can withstand reverse pulse voltage for a long time.
⑦The dielectric loss is small, the temperature characteristics are good, and it can work at 120℃ for a long time.
⑧Small size, long use time, no acid pollution.
⑨Can be stored for a long time.
