TGHG Series
Precision Current Sense Resistors
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.
F e aT u r e S
• 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

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.
