Bottom of base plate Temperature, ° C

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

THIS PRODUCT IS DESIGNED FOR USE WITH

PROPER HEATSINKING. Maximum base plate tempera-

ture of the resistor must be monitored and kept within specified

limits to establish the power rating. Best technique is to attach a

thermocouple to the side of the base plate of the resistor. Tempera-

ture of plastic housing or heat sink cannot be used to establish rating

of the resistor.
