Electrically Insulated

Thermal Conductivity Silicone Rubber Sleeve Electrically Insulated

Item Description

Thermal Insulation Silicone Caps, specifically crafted for TO-220/TO-3P packages, are molded from silicone using a specialized production process. With attributes such as high thermal conductivity, insulation, shock resistance, and easy assembly, these caps are widely employed in applications involving heat transistors, diodes, and triodes. Their adaptability allows for direct mounting on heating pipes, catering to scenarios with low pressure.
