Dielectric pads

CHO-THERM® insulating pads were developed as a user-friendly alternative to greased mica insulators to be used between discrete power devices and heat sinks.

  • Silicone binder provides high temperature stability and good electrical insulation properties
  • Glass mesh reinforcement provides cut-through resistance
  • High mounting pressure required to minimize contact resistance
  • U.L. recognized flammability ratings

This class of product is characterized by high thermal conductivity, very high dielectric strength and volume resistivity. Pads must conduct very large heat loads from discrete power semiconductors to heat sinks, while providing long-term electrical insulation between the live component case and the grounded heat sink.
