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 TH in F i LM?

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)

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 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.
