Seifert insulating discs made of Kapton are a good alternative to the fragile mica discs. They are used for insulation between heat sink and semiconductor component.
Together with the Seifert insulating sockets an optimal semiconductor mounting is guaranteed.
The Kapton insulating disks are available for different housing designs and have a thickness of 0.05mm. The dielectric strength is 280 KV/mm.
The foils are high-strength, good heat conductors and self-extinguishing.
