N045 – Electrical Insulating Thermal Film- Yellow

N045 is an electric insulating thermal conductive polyimide film with a thermal conductive phase change material (PCM) coating, suitable for use between a heat sink and a variety of heat dissipating components. N045 is also available with one side adhesive

N045 can be supplied in die-cut shapes for use in a wide range of electronic applications. The film is available in 0.025mm and 0.051mm

Ordering Example
  • N045-00510051-A0 N = Electric insulator / 045 = 0.45 W/mK / 0051 = 0.051mm
  • A0 = without adhesive / A1 = with adhesive on one side
