Type SR Precision Current Sense Resistors, ± 1.0% Tolerance
Standard Tolerance: 1%
Temperature Coefficient:
TC ref. to +25°C, ΔR taken at –15°C and +105°C
0.081 Ohm to 1.00 Ohm: –50 to +100 ppm/°C
0.025 Ohm to 0.080 Ohm: 0 to +150 ppm/°C
0.008 Ohm to 0.024 Ohm: 0 to +200 ppm/°C
Power Rating: The power rating should be limited as shown in the Derating Curve based on the maximum ambient temperature. The Derating Curve is based on still air with natural convection around the resistor.
Measurement Note: For these specifications, resistance measurement shall be made using Kelvin (4-wire) connections with appropriate current and sense connections to the resistor terminals.
Circuit Board Layout: The circuit board traces connecting to the current terminals must be sized appropriately for the current flowing through the trace to avoid excessive heating of the trace. For example, an 0.008 ohm resistor operated at 2.0 watts would have 15.8 amps flowing through the circuit board traces into the current terminals.
