jb Film Capacitor

This capacitor is small, with long lifespan and good self-healing ability. It is widely used as the start-up and running capacitor, especially for micro water pumps, cleaning machines, washing machines, and single-phase water pump motors.


jb film capacitors offers a full voltage range, from 63VDC to 2000VDC; our high voltage film capacitors include JFP (epoxy coating dipped type) and JFQ (box type) two series. JFA mylar polyester film capacitors, 1000V, 1200V is very popular. Also AC voltage and DC voltage both available, AC type film capacitors include JFC (AC metallized polyester film capacitors), JFN & JFO X2 class and JFT X1 class......

Tolerance range: ±1%, ±2%, ±2.5%, ±5%, ±10%

Temperature range: normally film capacitors temperature range is -40'C to 85'C, for some series we can provide a wide temperature range up to 125'C.

jb film capacitors technology available: winding technology and stacked technology (JFJ mini box series); single side metallized structure and double sided metallized structure (JFQ series) Safety Approvals of film capacitors: UL, TUV, CE, VDE...., X2 class, X1 class

Packaging: Ammo packaging and Bulk packaging both available, and all jb film capacitors are RoHS compliant

jb Plastic Film Capacitor—Dielectric Types

Film Capacitors are Non polarized, and may be used in AC or DC circuits.
Typical values range form 1000pF to 1uF for Polyerster Film, and 0.01uF to 18uF for Metallized Film capacitors. Standard Film Capacitor values change in multiples of 10, 12, 15, 18, 22, 27, 33, 39, 47, 56, 68, 82.

Normal Temperature Coefficient [TC] for Film Capacitors is +7%.

  • Mylar: has a wide temperature change of 20% over -55 to +125°C. Moisture absorption is half that of paper.
    Mylar is the same as polyester. The term Mylar is a trade name.
  • Polycarbonate: Out performs Mylar in all areas. Low Power factor, works best with AC. Polycarbonate has a low temperature drift (graph below), dissipation factor, and dielectric absorption. Use polyphenylene sulfide as a possible replacement.
  • Polyester: Replaces paper for many applications, and smaller in size. Polyester does not have the moisture problem that paper does, but does have a worse tolerance, at 20% ~ over -55 to +125°C. May also be called PETE, or PETP. The Polyester Dielectric has an Absorption of around 0.20%.
  • Polypropylene: It has negative temperature coefficient.
  • Polysulfone: Has a very high operating temperature of +170°C.
  • Polystyrene: Will only work to +65°C. It has a flat to negative temperature coefficient.
  • Teflon: Has a very high operating temperature of +170°C.

jb the Features of Film Capacitors

The features of film capacitor are non-inductive construction, self-healing, high reliable and superior performance in high frequency applications. It is applied to filter and noise suppression circuit, pulse logic and timing circuit, DC blocking, by-passing and signal coupling in general communication equipment. The construction of film capacitor includes polyester film dielectric with vacuum-evaporated metal electrodes, radial leads of tinned wire are electrically welded to the contact metal layer on the ends of capacitor winding, epoxy resin coating.
