• Resistance values beginning at 0.5m

Ω

• Non Inductive

• Four terminal Kelvin connection

• SOT 227 Package

• Four terminals to isolate measurement path

from current flow path

• Accuracy in a high power package

Best results can be reached by

using a thermal transfer compound

with a heat conductivity of better

than 1W/mK

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.

The TGHG Series uses

state of the art technol-

ogy to provide highly

reliable, non inductive

performance. This resis-

tor is ideal for many

current monitoring and

controls applications.
