Thermals: CHO-THERM® – T441

CHO-THERM® T441 low-cost thermally conductive insulators are designed for applications requiring a high level of dielectric breakdown protection. CHO-THERM® T441 pads provide good thermal conductivity and extremely high electrical insulation, even when used in humid enviroments. Surviving under most enviromental conditions, and filled fiberglass cloth, these pads provide maximum resistance to tear and does not promote fungal growth.

Critical Performance Characteristics

There are generally two objectives that must be satisfied in the interface between power semiconductor devices and their heat sinks:

  1. To Enhance the flow of heat from the device to the metal heat sink.
  2. To electrically isolate the device from the metal heat sink.

CHO-THERM® T441 insulators perform both functions simultaneously, effectivly replacing the commonly used combination of ceramic insulators and silicone grease usually required to achieve these objectives in high performance applications.
