Power Chip

Thick Film on Alumina Substrate

Ohmite’s original Power Chip resistors feature our

thick film on alumina substrate technology. These

planar packages yield space saving, 10W/in²power

densities that require over 50% less board space

than other radial packages. Convection cooling is

maximized by the planar package configuration

which dissipates heat well above board level.

Ohmite’s power chip resistors have a 125% higher

operating temperature range than competitive prod-

uct of similar design. High temperature solder and

in-process plating keep terminations secure under

self-heating effects by preventing re-flow from full

power operation.

• High-Temp Terminal Construction

• Wide Resistance Range

• Low Inductance (50nH-100nH)

• High Power Density

Flexible packaging schemes make these resistors

ideal for power supplies, audio amplifiers, video fly-

back, and other power control applications.

• Easy to install. PC-mountable
