Questions with Film Capacitors

  • Ask: What is a film capacitor used for?

    Answer: PP film capacitors are used for high-frequency high-power applications such as induction heating, for pulsed power energy discharge applications, and as AC capacitors for electrical distribution. The AC voltage ratings of these capacitors can range up to 400 kV.

  • Ask: Do film capacitors go bad?

    Answer: Polyester film capacitors are generally quite reliable unless repeatedly pushed to their dielectric breakdown threshold, which should not ordinarily happen in normal use (you would typically expect that to happen only with large surges or lightning strikes) provided they were properly spec'd to begin with.

  • Ask: Do film capacitors have polarity?

    Answer: The large, 20,000 µF electrolytic unit shown in the upright position has its positive (+) terminal labeled with a \u201cplus\u201d mark. Ceramic, mylar, plastic film, and air capacitors do not have polarity markings, because those types are nonpolarized (they are not polarity sensitive).

  • Ask: How do you test a film capacitor?

    Answer: To test the capacitor with a multimeter, set the meter to read in the high ohms range, somewhere above 10k and 1m ohms. Touch the meter leads to the corresponding leads on the capacitor, red to positive and black to negative. The meter should start at zero and then moving slowly toward infinity.
