Stackpole Electronics, Inc.
Resistive Product Solutions
Values from 0.003 to 0.1
Suitable for high current applications where standard
current sense resistor will not survive
Current handling up to 100 amps
Handles 1W to 5W of power
Various wire alloys and sizes allow for value, tolerance, and
TC flexibility; contact factory for specific combination of
alloy and Temperature Coefficient of Resistance.
