CP33- End Cap
- Low thermal contact resistance
- Electrically isolating
- Decrease the weight of the product
- Easy to assemble
- Thermal conduction and buffer effect
CP 22/23/33 is a end cap with 2 W/m•K thermal conductivity and buffer insulation characteristics, which is beneficial to use with transistors TO-220 and TO-247. It is easy to operate and convenient for production line assembly. It is used as a thermal interface material for transistors and aluminium heat sinks. The size can be customized to Chemical production.
