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.
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.
make these resistors ideal for
power supplies, audio ampli-
fiers, video fly-back, and other
power control applications.
F e A T u r e S
• High-Temp Terminal Construction
• Wide Resistance Range
• Low Inductance (50nH-100nH)
• High Power Density
• Easy to install. PC-mountable
