Transistor Mica Insulator Kit, TO-3, Pack of 10

Transistor Mica Insulator Kit, TO-3, Pack of 10 – These mica insulators are designed for use with TO-3 transistor packages, providing effective electrical isolation between the transistor and heatsink. Each kit includes 10 insulators, making it a convenient solution for multiple installations or maintenance work.

The insulator body is made from high-quality mica, offering excellent dielectric properties. With a breakdown voltage of 1kV and an isolation voltage of 1kV, these insulators are suitable for applications requiring reliable insulation between components. The TO-3 package case with a 6.35mm bush ensures compatibility with standard TO-3 mounting configurations.
