Precision Current Sense Resistors

The TGHG Series uses
state of the art technol­ogy to provide highly
reliable, non inductive
performance. This resis­tor is ideal for many
current monitoring and
controls applications.

CHARACTERISTICS

FEATURES

• Resistance values beginning at 0.5mΩ

• 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

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 es­tablish the power rating. Best technique is to attach a
thermocouple to the side of the base plate of the resis­tor. Temperature of plastic housing or heat sink cannot
be used to establish rating of the resistor.

Derating

Best results can be reached by
using a thermal transfer compound
with a heat conductivity of better
than 1W/mK
