Conventional type high-frequency transformer wire frame

Conventional type high-frequency transformer wire frame (BOBBIN) mainly uses bakelite powder material as the basic material, such as Changchun company's T373J material, T375J material, Sumitomo company's PM9820 material, PM9630, LCP material, etc. The material is brittle and fragile, the fire rating is 94V-0, especially high temperature resistance (370 degrees), the voltage resistance is about 10KV/mm, and the surface is smooth. It can be said that bakelite is the most used material in transformers, because it has high temperature resistance, no deformation, medium voltage resistance, and is suitable for large and medium-sized power transformers.
