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

TK20 = 20W thick film (TN15 only) Example:
TN15 = 15W thin film P = ±50ppm R075= 75mΩ G= 2%
L = ±25ppm 7R50= 7.5Ω J = 5%
V = ±10ppm 75R0= 75Ω
X = ±5ppm 7K50 = 7500Ω
• Low Cost
0.900"
• Thin Film Construction is the
first Thin Film power resistor in
heatsinkable packaging on the
market.
