## Micro Porous Ceramic Heat Sinks (MPCHS) 

- **Non electrically conductive, no antennae effect.** 

- **Low Profile, light weight.** 

- **Large surface area compared to Aluminium Heat Sinks.** 

- **With and without thermally conductive Silicone adhesive tape.** 

- **Low cost.** 

The structure of the Micro Porous Ceramic Heat Sink provides a very large surface area compared to conventional Copper and Aluminium Heat Sinks. Even though the thermal resistance of the Ceramic is much higher than Aluminium because of the micro porous structure it provides excellent heat dissipation and heat convection. It also provides low thermal capacity in unit volume compared to Copper and Aluminium Heat Sinks. The MPCHS dissipates heat faster than metal Heat Sinks without storing heat within itself.
