TNP10 Series
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.

Maximum base plate temperature of the resistor
must be monitored and kept within speci-
fied 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.
