C. Capacitance change over temperature is 4 times better than with polypropylene. The best electrical properties of all the Dielectrics. Paper or Kraft Paper is the oldest of the film capacitor dielectrics. The paper must be impregnated with Epoxy, Wax, Oil, or other suitable impregnate. It is still popular for high voltage and AC rated capacitors operating at lower frequencies.
Paper is also wound with plastic dielectrics in combination dielectric capacitors.
