TGHGCR0750FE Ohmite

TGHG Series Precision Current Sense Resistors Fea TureS The TGHG Series uses Resistance values beginning at 0.5m state of the art technol- Non Inductive ogy to provide highly Four terminal Kelvin connection reliable, non inductive performance. This resis- SOT 227 Package tor is ideal for many Four terminals to isolate measurement path current monitoring and from current flow path controls applications.

Range -55C to +155C than 1W/mK Max. Torque for Contacts 1.3Nm 8 (static) Max Torque for Base Plate 1.5 Nm (static) 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.
