Procurement Notes

Verify the specific part number suffix against official Bourns documentation to confirm electrical characteristics and packaging details. Ensure compatibility with automated placement equipment regarding the 1260 footprint. Confirm RoHS compliance status if required by your manufacturing process. Cross-reference datasheet values for thermal performance under actual load conditions before finalizing procurement.

Selection Notes

Select this component when a compact dual-inductor solution is needed for SEPIC converters or coupled applications. The 1260 package size balances current handling capability with board space constraints. Consider the 2.7 A rating and 32.9 mΩ resistance for efficiency calculations. Verify that the 15 µH value aligns with the target switching frequency and ripple current requirements of the design.

Part Context

The SRF1260 series consists of dual-winding shielded power inductors manufactured by Bourns Inc. These components are engineered for high-current applications requiring magnetic shielding.
