Best technique is to attach a ther- 0 mocouple to the side of the base plate of the resistor. 0 25 50 75 100 125 150 175 Temperature of plastic housing or heat sink cannot be Bottom of base plate Temperature, °C used to establish rating of the resistor. 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 (continued) 152 1-866-9-OHMITE • Int’l 1-847-258-0300 • Fax 1-847-574-7522 • www.ohmite.com • info@ohmite.com
