New to me is a heatsink made of microporous copper foam (according to the
manufacturers blurb).=20

For passive uses only, they state in their datasheet that a 40 * 40 * 5mm=20
microporous heatsink has a thermal resistance of 17.4 C/W with a 5W load.=20
They have compared it to a silver heatsink, however looking at a black=20
heatsink listed at E14, the CCI11 has a thermal resistance of 9.38 to 5.14 =
=20

K/W.

Versarien unfortunately do not specify the testing conditions they uses.

The microporous heatsink was last weeks product news in the Elektor=20
newsletter.
