Frequently Asked Questions

Q: What sizes are included in the 100-pack of TO-220 Silicone Mica Insulation Pads?

A: The pack includes two sizes — 13×18×0.12mm and 18×22×0.12mm — both at an ultra-thin 0.12mm thickness, making them suitable for a wide range of TO-220 package components such as transistors and voltage regulators.

Q: What is the purpose of a TO-220 Silicone Mica Insulation Pad?

A: These insulation pads are placed between a TO-220 component (like a power transistor or voltage regulator) and a metal heat sink. They provide electrical isolation to prevent short circuits while still allowing heat to transfer efficiently from the component to the heat sink.

Q: Are these silicone mica pads reusable?

A: Yes, the flexible silicone mica material is durable and can typically be reused, though for best electrical isolation performance in critical applications, using a fresh pad each time is recommended.
