Thin Film TO-126 Resistor
Ohmite offers a high power heatsinkable TO-126 packaged
resistor. They can achieve 1W in free air and 10W when
attached to a proper heatsink. The non-inductive design is ideal
for high speed circuits. These models exhibit low noise, high
frequency operation and high density installation. Applications
include: Constant current sources, electronic load circuits, LSI
tests, measurement, audio PA systems and motor control.

Coonstruction
THIS PRODUCT IS DESIGNED
FOR USE WITH PROPER
HEATSINKING.
Maximum base plate temperature of the resistor
must be monitored and kept within specified limits to establish the power rating. Best
technique is to attach a thermocouple to the side
of the base plate of the resistor. Temperature of
plastic housing or heat sink cannot be used to
establish rating of the resistor.
