5TH21000

For an efficient cooling of power components, 5TH21000 is usual to apply a thermally conducting media, such as thermal grease, between the power element and the heatsink.

Thermal grease of 5TH21000 is considered problematic due to difficulties in applying it to the heatdissipating surface and also performances in the life of the product.

An alternative, celduc tested a range of products and compared their thermal resistance characteristics (Rth c/h : Thermal Resistance between case to heatsink) celduc recommends Aluminium materials thermal pads with very good thermal performances and no modification in the long term.
