Ohmite offers the totally encap-

sulated 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.

F e A T u R e s

• 100 Watt power rating at 25°C

• Non-inductive performance

• Low thermal resistance

• RoHS compliant design

• TO-247 package configuration

• Single screw mounting simplifies

• A totally molded housing for envi-

• Non-Inductive design

• Resistor package totally insulated

D e R A T i n G

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
