Fixed Inductors Procurement Notes

Verify the specific suffix 'M' indicates tape-and-reel packaging configuration as per manufacturer standards. Confirm RoHS compliance status through official documentation prior to integration. Ensure ordering quantities align with standard reel sizes defined by Bourns for this series. Cross-reference the datasheet revision date to guarantee parameter accuracy against current production batches.

Fixed Inductors Selection Notes

Select this component when a low-profile, semi-shielded inductor is required for automotive-grade circuits. The 8.2 µH value suits specific filtering needs in DC-DC conversion. Consider the 1.3 A DC current rating and 1 A saturation limit for load requirements. The 1212 footprint allows for compact board designs while maintaining thermal performance within the specified temperature range.

Fixed Inductors Part Context

This part belongs to the SRN3010BTA series, which targets compact power supply stages requiring semi-shielded inductors. The series is characterized by its automotive qualification and enhanced product reliability. It complements other Bourns components like the SRP2512CL and SRP3212CL series in providing efficient power delivery solutions for modern electronic systems.

Fixed Inductors Replacement Considerations

Direct substitutes within the same series include SRN3010BTA-150M and SRN3010BTA-470M, differing primarily in inductance values.
