I was poking around on Bergquist's web page looking at various Sil-Pad that they manufacture and came across some information that I can't quite understand and was hoping that someone would help me out.
I'm looking for Sil-Pads for mounting the Mosfets for my Aleph-X to the heatsink. But, I can't tell which of these two products would be better for between the Mosfet and the heat sink.
Sil-Pad A2000 : Thermal Impedance = 0.32, Thermal Conductivity = 3.0
Sil-Pad 1500ST : Thermal Impedance = 0.23, Thermal Conductivity = 1.8
If you go by Thermal Impedance, it appears that the 1500ST is the better product, but if you look at Thermal Conductivity, it appears that the A2000 is the better product.
So which on would be better to use? The Aleph-X that I want to build will be near 150w into 4 ohms, so it looks like every last little bit of keeping those Mosfets cool is worth the effort.
Can anyone explain Thermal Resistance vs. Thermal Conductivity and indicate which product is a better choice?
Thanks!
Eric
