Derating (thermal resistance): 0.666W/°K (1.5K/W). Without a heatsink, when in
free air at 25°C, the TEH100 is rated for 3.5W. Derating for temp. above 25°C is
0.0234W/°K.
Graphed value is only valid when using a thermal conduction to the heatsink Rth-
cs<0.025°K/W. This value can be reached by using thermal transfer compound
with a heat conductivity of 1W/mK. The flatness of the cooling plate must be better
than 0.05mm overall. The roughness of the surface should not exceed 6.4µm. The
case temperature is to be used for the definitiion of the applied power limit. The
case temperature measurement must be made with a thermocouple contacting
the center of the component mounted on the designed heat sink. Thermal grease
should be applied properly
