Procurement Notes

Verify the specific suffix 'M' indicates the required tolerance level. Confirm package dimensions match the PCB footprint requirements. Ensure thermal management aligns with the specified operating temperature range. Check for RoHS compliance documentation if required by local regulations.

Selection Notes

Select this component when dual independent windings are necessary within a compact form factor. Consider the 3.28 A RMS rating for continuous load conditions. Evaluate the 61.8 mΩ DCR impact on overall efficiency. Verify compatibility with automated surface mount assembly processes.

Part Context

This part belongs to the SRF1260 series of dual-winding shielded power inductors manufactured by Bourns. The series is characterized by its low-profile 1260 package size, making it suitable for applications requiring high current density in limited board space. The technology utilizes wirewound construction on a ferrite core for reliable power handling.

Replacement Considerations

Direct substitutes include other SRF1260 series variants with different inductance values or current ratings. Cross-reference with similar dual-winding shielded inductors from other manufacturers only if pinout and dimensional specifications are identical.
