Can polypropylene film capacitors replace electrolytic capacitors?

They can replace electrolytic capacitors in applications where the voltage is above 500V. RS have a great range of capacitors including these polypropylene film capacitors in various capacitance, voltage ratings and tolerances for all your electronics needs.

What is a Polytetrafluoroethylene film capacitor?

Polytetrafluoroethylene film capacitors feature a very high temperature resistance up to 200 °C, and even further up to 260 °C, with a voltage derating. The dissipation factor 2 • 10 −4 is quite small. The change in capacitance over the entire temperature range of +1% to -3% is a little bit higher than for polypropylene film capacitors.

What are the electrical parameters of polypropylene film capacitors?

The temperature and frequency dependencies of electrical parameters for polypropylene film capacitors are very low. Polypropylene film capacitors have a linear, negative temperature coefficient of capacitance of ±2,5 % within their temperature range.

What is a good axial polypropylene film capacitor?

Good quality, great value axial polypropylene film capacitors from 1uF to 300uF rated at 250Vdc. Suitable for cross-overs and other low- to mid- The world-reknown Jensen capacitors from Denmark make superb aluminium foil, paper in oil, Copper foils, axial and radial electrolytics. Great for

What is a polyester film capacitor?

Polyester film capacitors are film capacitors using a dielectric made of the thermoplastic polar polymer material polyethylene terephthalate (PET), trade names Hostaphan or Mylar, from the polyester family. They are manufactured both as metallized wound and stacked versions, as well as film/foil types.

Why are polypropylene film capacitors used in resonant circuits?

Polypropylene film capacitors are specified because of their low electrical losses and their nearly linear behavior over a very wide frequency range, for stability Class 1 applications in resonant circuits, comparable only with ceramic capacitors.
