Patent pending
Ohmite is proud to introduce
the newest addition to our
family of Heat Sinkable Power
Resistors. The TK/TN Series
offers 3 major advances over
existing TO-220 products:
• Low Resistance Values down
to 0.03 ohms for current sense
applications
• Low Cost
• Thin Film Construction is the
first Thin Film power resistor in
heatsinkable packaging on the
market.

WHY THin FiLM?
Thin film technology offers the fol-
lowing performance advantages:
• Extremely stable (low TCR)
• Low Noise (parasitic capacitance
and resistance)
• Excellent High Frequency
Performance
• High Accuracy (tight tolerances)

Maximum base plate temperature of the resistor must
be monitored and kept within specified limits to es-
tablish the power rating. Best technique is to attach a
thermocouple to the side of the base plate of the resis-
tor. Temperature of plastic housing or heat sink cannot
be used to establish rating of the resistor.
