Typical Characteristics and Graphs of the Polyester (PET) Film

Metallized Polyester Type

SMD-PET

Typical Applications

For general DC-applications e.g.
  • By-pass
  • Blocking
  • Coupling and decoupling
  • Timing

Film Properties

  • Dielectric constant at 1kHz and +23°C: 3.3 positive as temperature rise
  • Specific volume resistance in Ωcm at +23°C: 1018
  • Dielectric strength (DC voltage) in V/µm at +23°C: 580
  • Preferred temperature range in °C: -55 to +105 (+125)
  • Dielectric absorption in % at +23°C: 0.20 to 0.25
