SRF1260A-470M

Overview

The Bourns SRF1260A-470M is a shielded dual-coil power inductor array from the SRF1260 series, featuring ferrite core construction. It offers an inductance of 188 µH when coils are connected in series and 47 µH when connected in parallel. The component has a DC resistance of 86 mΩ and a rated current of 3.24 A. It operates within a temperature range of -40°C to +125°C and utilizes a surface-mount 1260 package measuring 12.5 x 12.5 x 6 mm.

Feature Summary

• Dual-winding architecture allows flexible series or parallel configuration for varying inductance requirements.
• Shielded design minimizes electromagnetic interference and magnetic flux leakage.
• Ferrite core material supports high-frequency operation with stable performance.

Applications

• DC-DC converter output filtering
• Power supply input stages
• Automotive electronics systems

Procurement Notes

Verify the exact part number suffix against official Bourns documentation to confirm pinout and tolerance specifications. Ensure the ordering code matches the required inductance configuration (series vs. parallel) as defined in the datasheet. Cross-reference manufacturer lot codes for quality assurance and traceability requirements specific to your manufacturing process.

Selection Notes

Select this component when a compact dual-inductor solution is needed for space-constrained designs. The 1260 footprint provides a balance between current handling capability and board area efficiency. Consider the 3.24 A rating and low DCR for applications requiring efficient power conversion with minimal thermal generation.

Part Context

This component belongs to the Bourns SRF1260 series of automotive-grade shielded power inductors. The series is designed for high-current applications in demanding environments. The SRF1260A variant specifically denotes the dual-coil array configuration, distinguishing it from single-coil counterparts in the same physical package family.

Replacement Considerations

Direct substitutes include other Bourns SRF1260 series parts with matching electrical characteristics. Verify that any replacement maintains the same 1260 package dimensions and shielding type to ensure mechanical compatibility.
