Without a heatsink, when in free air at 25C, the TEH100 is rated for 3.5W. Derating for temp. above 25C is 0.0234W/K. Graphed value is only valid when using a thermal conduction to the heatsink Rthcs<0.025K/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 6.4m. 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 Percent Rated Power check product availability using the Worldwide inventory search at ohmite.com Ohmite Mfg.
