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.
