Procurement Notes

Verify the specific suffix 'Y' or 'M' against the datasheet, as these often denote tolerance or packaging variations. Confirm the manufacturer's standard lead time, which may extend significantly due to supply chain constraints. Ensure the ordering quantity matches the available tape and reel specifications provided by the distributor. Cross-reference the RoHS compliance status with current environmental regulations before finalizing procurement.

Selection Notes

Select this component when high current handling and compact footprint are required in automotive environments. Compare the parallel and series current ratings against the circuit's peak load requirements. Evaluate the saturation current limits to ensure stable operation under transient conditions. Consider the thermal performance at the specified operating temperature range to maintain efficiency.

Part Context

This part belongs to the SRF1260A series of dual-winding shielded power inductors from Bourns. The series is characterized by its robust construction and suitability for demanding automotive electronics. It shares the same physical dimensions and mounting style with other variants in the SRF1260 family, allowing for design flexibility across different inductance values.

Replacement Considerations

Direct replacements include other SRF1260A series variants with similar inductance and current ratings.
