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/in2 power
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
