Ohmite’s original Power Chip

resistors feature our thick film

on alumina substrate technol-

ogy. These planar packages

yield space saving, 10W/in²

power densities that require

over 50% less board space

than other radial packages.

Convection cooling is maxi-

mized by the planar package

configuration which dissipates

heat well above board level.

Ohmite’s power chip resis-

tors have a 125% higher oper-

ating temperature range than

competitive product of similar

design. High temperature

solder and in-process plat-

ing keep terminations secure

under self-heating effects by

preventing re-flow from full

power operation.
