Paper Capacitor

Paper Capacitors are typically constructed of flat thin strips of metal foil conductors that are divided by waxed paper. Paper capacitors are sealed with wax to prevent the harmful effects of moisture and to prevent corrosion and leakage. Paper capacitors usually vary in value from about 300 picofarads to about 4 microfarads. The working voltage of a paper capacitor rarely exceeds 600 volts.

Dearborn Electronics manufactures paper capacitors that include paper / polyester capacitors, paper foil capacitor, paper / polyester foil capacitors and high voltage paper / polyester foil capacitors. Besides these standard paper capacitors, Dearborn Electronics has the ability to custom design paper capacitors for your particular need.
