56-03-8G Description

Short technical summary and product information.

The 56-03-8G is a mica insulator pad designed for use with TO-3 transistor packages. It features a rhombus shape with an outline of 42.85mm x 30.15mm and a thickness of 0.051mm (0.0020 inches). The opaque mica material provides electrical insulation between the transistor and heatsink while maintaining thermal conductivity. This insulator is RoHS3 compliant and has a moisture sensitivity level of 1 (unlimited). It is a direct replacement for standard TO-3 insulator pads. Manufactured by Aavid, Thermal Division of Boyd Corporation, a leader in thermal management solutions.
