Polyester Film Capacitors

Polyester film capacitors are types of capacitors (devices made of one or more pairs of conductors separated by an insulator, used to store an electric charge), where polyester film (PET) is used as the insulating material. This type of capacitor is mainly used as a general-purpose capacitor. 


Applications for polyester film capacitors

Polyester film capacitors are low cost, usually small in size, and still have relatively high capacitance values. They're mainly used as for DC (direct current) applications, or for semi-critical circuits. 


Key characteristics of polyester film capacitors

  • High dielectric (insulator) strength – the polyester dielectric used in these capacitors (also referred to as PET or mylar) offers a high level of insulation.
  • Operating temperature – as a result of the properties of the polyester dielectric, these capacitors are often able to operate up to temperatures of 125°C. 
  • Tolerance – many polyester film capacitors have a tolerance of only 5% or 10%, but this is adequate for plenty of applications where insulation strength or temperature resistance are of greater concern.
