Thermal Insulating Pads

A user-friendly insulator between discrete power devices and heat sinks; conducting very large heat loads and maintaining electrical insulation between heat sinks and components.


Cho-Therm: thermally conductive electrical insulator pads are designed for use where the highest possible thermal, dielectric, and mechanical properties are required. These products are designed for use as alternatives to greased mica insulators between discrete power devices and heat sinks, offered as dry pads or with an optional acrylic adhesive (PSA) layer for attachment.
