Ohmite’s original Power Chip
resistors are designed from our
thick film on alumina substrate
technology. These planar pack-
ages 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

Flexible packaging schemes
make these resistors ideal for
power supplies, audio ampli-
fiers, video fly-back, and other
power control applications.
Maximum Operating Voltage:
