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.
W H Y T H I N F I L M ?
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)
