Paper film capacitor

The paper film capacitor is made of wax impregnated paper. It has a high dielectric constant and a high pulse tolerance. The high pulse tolerance means that it can be charged and discharged quite rapidly without becoming hot and starting to burn. But they are large and more expensive than plastic film capacitors.

Today the paper film capacitor has been replaced in most applications by the plastic film capacitor, and is now most used in noise filters, due to better characteristics for this than the plastic film capacitor.
Some capacitors have a combined plastic and paper dielectrics, and are called mixed dielectricum capacitors. These have a combination of the advantages of the two types.
