Paper Capacitors

Paper capacitors are a type of capacitor with a layered construction of aluminium sheets separated by waxed or oiled paper sheets. The paper between the aluminium acts as the dielectric (insulating) material. Some paper capacitors feature a cardboard cover while others are encapsulated in hard plastic. RS Components have a broad range of paper capacitors that covers an expansive set of capacitances and voltages, with products from industry leading brands such as KEMET and Cornell-Dubilier.

What do capacitors do?

Capacitors are a type of passive component that stores an electrical charge. The more charge a capacitor can store, the larger its capacitance is. Capacitance is measured in denominations of farads – such as microfarads or picofarads.

What are the advantages and disadvantages of paper capacitors?

  • Paper capacitors have a high working voltage and a high capacitance range. They are suited to high voltage and high current applications.
  • The paper dielectric provides excellent stability and reliability of the component.
  • Paper capacitors tend to have high leakage rates, making them unsuitable for applications such as AC coupling.
  • Paper capacitors typically have tolerances between ±10% and ±20%, making them unsuitable for precision timing circuits.
