Procurement Notes

Verify the specific package variant and tape/reel specifications against the manufacturer's latest datasheet before ordering. Confirm that the voltage rating and thermal performance meet your system requirements. Ensure compatibility with your PCB footprint and reflow soldering profile to maintain component integrity during assembly.

Selection Notes

Select this component when space-constrained designs require high-current shielding. Compare parallel versus series inductance needs based on your switching frequency. Verify thermal dissipation capabilities under maximum load conditions. Ensure the physical dimensions fit within your enclosure constraints.

Part Context

Part of the SRF1260 series from Bourns Inc., this component belongs to a family of shielded power inductors. The series offers various inductance values optimized for compact power management solutions. It shares design characteristics with other SRF models but differs in specific electrical ratings and pin configurations.

Replacement Considerations

Check equivalent part numbers from Bourns such as SRF1280-470M for dimensional differences. Verify inductance and current ratings match your design requirements. Ensure pinout compatibility if substituting directly on existing PCB layouts.
