TO-220,TO 3P Thermal Conductivity Cap and Tubes
Description
Thermal insulation silicone cap is set as the substrate, through a special process from production cap-like products. Because of their excellent thermal conductivity, insulation, shock-anti ,convenience to equipment and other characteristics, widely used in heating transistors, diodes, transistors.
Thermal insulation caps - main feature:
Excellent thermal conductivity
High insulation, shock resistance
Fire prevention, Eco-friendly environmental protection
Friction and compression endurance
Meet ROHS, REACH and UL94-V0 grade
Typical application
1. fever transistor
2. diodes, three tubes
3. IGBT MOSFET
It is widly used for thermal conductivity, electrical insulation for power transistors and power modules. Its additional ability to dampen vibrations makes them ideal for semiconductor devices such as CPU’s and electrical components. The ability to dissipate large amounts of heat enhances their use for thermal fuses and temperature sensors.
