Ohmite offers the totally
encapsulated and insulated
TO-247 package for low
ohmic value and non-induc­tive design for high-frequen­cy and pulsing applications.
Ideal use is for power sup­plies. This series is rated
at 100 Watts mounted to a
heat sink.

THIS PRODUCT IS DESIGNED FOR
USE WITH PROPER HEATSINKING.

Maximum base plate temperature 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.
Temperature of plastic housing or heat sink cannot be
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 Rth­cs<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
