Ceramic Heat Sink: CECD Series

Porous ceramic heat sink with excellent insulation.

  • Compared to traditional aluminum, the combination of the larger surface area provided by the porous structure and higher levels of thermal radiation amounts to superior heat dissipation.
  • About 30% lighter than aluminum heat sinks.
  • There is no electromagnetic radiation from the heat sink unlike conventional metallic ones.
  • Operating temperature -40 ~ 125°C

EMI issue with metalized heat sink

Metal HS: EMI issue with metalized heat sink

Metal heat sink becomes an antenna and receives electronic noise. Due to electrostatic coupling noise current shifts from IC and creates radiation noise.

Ceramic: EMI issue with metalized heat sink

Due to superb insulation Ceramic heat sink has no effect by electrostatic coupling or EMC noise.
