Thick Film Power Surface Mount
Ohmite’s TDH resistor is an economical solution to intermediate power
application design requirements.
TDH’s reliable thick film on alumina
substrate construction can be easily
heat sinked for higher power performance. TDH resistors are ideal for
pulse-loading, pre-charge, bleeder,
and snubber applications.

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

THIS PRODUCT IS DESIGNED FOR
USE WITH PROPER HEATSINKING.
Maximumbaseplatetemperatureoftheresistormust
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.
