SRF1280-1R5Y

Overview

The Bourns SRF1280-1R5Y is a dual-winding shielded power inductor array designed for surface-mount applications. It features an inductance of 1.5 µH when connected in parallel and 6 µH in series, with a tolerance of ±30%. The component supports a parallel current rating of 13.5 A and exhibits a DC resistance of 7.6 mΩ. Housed in a compact 1280 metric package, it is engineered for high-power density environments requiring stable magnetic shielding.

Feature Summary

• Dual-winding architecture optimized for coupled inductor topologies
• Integrated magnetic shielding to minimize electromagnetic interference
• Surface-mount design facilitating automated assembly processes

Applications

• SEPIC converter circuits
• Communication equipment power supplies
• Computer system power distribution

Procurement Notes

Verify the specific suffix 'Y' against official Bourns documentation to confirm tape-and-reel packaging specifications. Ensure the selected variant matches the required inductance configuration (series or parallel) for the target circuit design. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Selection Notes

Select this component for designs requiring coupled inductors with high current handling capabilities. The dual-winding structure is particularly suitable for SEPIC topologies where magnetic coupling improves efficiency. Evaluate the thermal performance under maximum load conditions, as the compact 1280 package relies on PCB copper area for heat dissipation during continuous operation.

Part Context

This component belongs to the Bourns SRF1280 series of shielded power inductors. The series provides various inductance values and current ratings within a standardized footprint. These inductors are widely used in modern electronics where space constraints and electromagnetic compatibility are critical design factors for power management solutions.

Replacement Considerations

Consult official Bourns substitution guides for direct equivalents. Verify that any alternative maintains identical winding configurations, core materials, and physical dimensions to ensure board compatibility and electrical performance parity.
