Typical Characteristics and Graphs of the Polyester (PET) Film
Polyester Film and Foil Types
Metallized Polyester Types
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
