Ohmite’s original Power Chip
resistors feature our thick film
on alumina substrate technol-
ogy. These planar packages
yield space saving, 10W/in
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-
0.17"/4.32mm
ating temperature range than
competitive product of similar
design. High temperature
solder and in-process plat-
0.040" / 1.02 mm
ing keep terminations secure
under self-heating effects by
preventing re-flow from full
power operation.
0.240" /
Flexible packaging schemes
6.10 mm
make these resistors ideal for
0.300" /
7.62 mm
power supplies, audio ampli-
fiers, video fly-back, and other
0.070" /
power control applications.
