 Thermally Conductive Insulator / Round Thermal Conductive Insulator / Silicone Rubber Thermal Insulator

TO-220 thermal insulator is mainly used for heat spreading of electronic components. Tranditionally it use thermal grease and mica insulating pad for insulation and heat conduction, but now, TO-220 series thermal conductive insulator eliminates all inconveniences and greatly shorten your working time and improve working efficiency.

Application:
  • High power transistor
  • Field-effect transistor
  • Voltage regulator module(LM78 series, LM317 series, sanyo power supply)
  • Audio amplifier module(TDA series)
  • Integrated rectifier module
Typical Specifications:
  • TO-220 / TO-3P / TO-3 / TO-3P1 etc
Standard Packaging:

  • 1000pcs / bag
