The development prospects of film capacitors are promising, especially in recent years, as the number of people using film capacitors has continued to increase online. Why do film capacitors win such high praise? It is inseparable from their advantages. This article will tell you about the nine advantages of film capacitors! Let's learn together!
Film capacitors have replaced electrolytic capacitors as a market trend. 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. It is a trend to use film capacitors to replace electrolytic capacitors in DC filtering.
Nine advantages of film capacitors:
① Ability to withstand high current.
② Strong surge resistance.
③ It can withstand a 2.5KV spike voltage with a pulse width ratio of 1.2μs:50μs or 8μs:20μs between the rising and falling edges.
④ Capable of withstanding high peak current, small inductance, and fast charging and discharging speed.
⑤ High voltage resistance, can withstand overvoltage 1.5 times higher than the rated voltage.
⑥ Non-polar, can withstand reverse pulse voltage for a long time.
⑦ The dielectric loss is small, the thermal characteristics are good, and it can work for a long time at 120℃.
⑧ Small size, long life, no acid pollution.
① Can be stored for a long time.
