Spreadfast SF-CHS Series Finned Ceramic Heatsink


Spreadfast SF-CHS series of finned ceramic heatsinks have been designed as a lower density improvement over traditional metal heatsinks. The innate characteristics of ceramic heatsinks means the SF-CHS series have a high breakdown voltage and heat dissipation. Thanks to the meticulous design of these ceramic heatsinks, the SF-CHS series are ideally suited to applications where thermal cycling stability are required.

Typical Applications

Traditional heatsink replacement.

LED & chipset cooling.

Power modules.

IC cooling.
