Polypropylene capacitor

The Polypropylene capacitor are capacitors with metal foil as an electrode, which overlaps with polypropylene film from both ends and coils into a cylindrical structure.Polypropylene capacitor have the same principles as polyester capacitors: non-polar, high insulation resistance, excellent frequency characteristics (wide frequency response), and low loss of media.Based on the above advantages, polypropylene film capacitors are [...]

Precautions for capacitor use

1. Aluminum electrolytic capacitor is a two-polar structure (see the mark on the capacitor body). Please pay attention to the polarity when installing.Alternating current (ac) or the application of the reverse voltage may cause short circuit or a damaged capacitor circuit polarity may occur in the reverse or not sure, so the dual polarity capacitors is [...]
