Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct resistance and tolerance values. Confirm package type and terminal finish requirements match the target assembly process. Check for any recent product change notifications or end-of-life announcements directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when high thermal stability and low inductance are required in through-hole designs. The wide operating temperature range makes it suitable for harsh environments. Ensure the PCB layout accommodates the physical dimensions and provides adequate heat dissipation for the 5W power rating during continuous operation.

Part Context

This part belongs to the MSR series of wirewound current sense resistors. The series is characterized by coated wirewound technology designed for high-power current detection. These components offer low inductance and high precision, distinguishing them from general-purpose thick film resistors in high-current measurement scenarios.

Replacement Considerations

Consult official substitution guides for direct equivalents. Verify that any replacement maintains the same radial package, power rating, and temperature coefficient to ensure mechanical and electrical compatibility in existing designs.
