C = Current connection S = Sense connection Ordering Information: Circuit Board Layout: The circuit board traces connecting to the current terminals must SR10 - 0.050 - 1% be sized appropriately for the current flowing through the trace. For example 0.005 Tolerance Model Number: operated at 2.0 Watts would have 20 amps flowing through the circuit board traces into Resistor Value: the current terminals.
