Type SR Precision Current Sense Resistors Non-inductive Design - Compact Footprint Minimizes Circuit Board Space Kelvin Terminals (Four Wire) - Resistance Values 0.005Ω to 1.00Ω Type SR Current Sense Resistors utilize Caddock's Micronox® resistance films to achieve a low cost resistor with Non-inductive Performance. This compact construction makes this sense resistor ideal for many current monitoring or control applications. The special performance features of these Type SR Current Sense Resistors include: • Available in Standard Resistances down to 5 milliohm. • Non-Inductive Design. • Terminals are constructed for Kelvin connections to the circuit board. • Compact footprint.

C = Current connection S = Sense connection Circuit Board Layout: The circuit board traces connecting to the current terminals must be sized appropriately for the current flowing through the trace. For example; 0.005Ω operated at 2.0 Watts would have 20 amps flowing through the circuit board traces into the current terminals.
