The TGHG Series uses
state of the art technology to
provide highly reliable, non
inductive performance. This
resistor is ideal for many cur-
rent monitoring and controls
applications.
Precision Current Sense Resistors
TGHG Series
FEATURES
• Resistance values beginning at
0.5mΩ
• Non Inductive
• Four terminal Kelvin connection
• SOT 227 Package
• Four terminals to isolate mea-
surement path from current flow
path
• Accuracy in a high power pack-
