About Film Capacitors

Plastic film capacitors are insulated with polyester, polypropylene, polystyrene or other dielectric materials. Polyester film capacitors offer a high dielectric constant and high dielectric strength. Metallized polyester film capacitors provides excellent self-healing properties, allowing capacitors to withstand high-pulsed voltages without breaking the dielectric. Polypropylene film capacitors provide very low loss, low dielectric absorption, and high dielectric strength. They also offer very high insulation resistance and negative temperature coefficient. Polystyrene film capacitors provide extremely low losses, low dielectric absorption, good long-term stability, very high insulation resistance and a small negative temperature coefficient.

jb Capacitors produces more than 19 series of plastic film capacitors. Regarding Metallized polyester film capacitor, we offer standard dipped type metallized polyester film capacitor JFB, box type metallized polyester film capacitor JFD, AC voltage metallized polyester film capacitor JFC, Mini box stacked metallized polyester film capacitor JFJ. Besides, JFA mylar polyester film capacitors and JFH polyester film capacitors are famous due to its competitive prices and small size.

jb Capacitors has full range of plastic film capacitors. Prices are very competitive. Lead time is always short.
