SRF1280A-2R2Y

Overview

The Bourns SRF1280A-2R2Y is a dual-winding shielded power inductor array designed for surface mount applications. It features a ferrite core and wirewound construction within a 12.5 mm x 12.5 mm x 7.5 mm package. The component provides an individual coil inductance of 2.2 µH with a tolerance of ±30%. It supports a maximum DC current of 8.108 A and exhibits a maximum DC resistance of 9.2 mΩ per winding. Certified to AEC-Q200 standards, it operates reliably between -40°C and +125°C.

Feature Summary

• Dual-winding configuration with magnetic shielding to minimize electromagnetic interference
• Automotive-grade reliability certified under AEC-Q200 standards
• High saturation current capability suitable for high-power density circuits

Applications

• Automotive electronic systems requiring robust power filtering
• DC/DC converter input and output stages
• Power supply modules in harsh thermal environments

Procurement Notes

Verify the specific datasheet version to confirm electrical parameters, as manufacturer specifications may be updated. Ensure the ordering suffix matches the required packaging format, such as cut tape or reel, for your assembly line. Cross-reference the part number against official Bourns documentation to distinguish this dual-winding array from single-winding variants in the same series.

Selection Notes

Select this component when a compact dual-inductor solution is required for automotive or industrial power conversion. The 1280A footprint allows for high-current handling while maintaining low profile. Consider the ±30% tolerance and temperature stability when designing precise filter networks. Verify that the 8.108 A current rating meets the peak load requirements of the target circuit without exceeding saturation limits.

Part Context

This part belongs to the SRF1280A series of dual-winding shielded power inductors manufactured by Bourns Inc. The series is engineered for high-performance applications where space constraints and thermal management are critical. Unlike single-coil counterparts, these arrays integrate two independent windings in one package, reducing board area and simplifying layout for differential or multi-phase designs.

Replacement Considerations

Direct substitutes include other SRF1280A series variants with identical pinout and similar inductance values, such as SRF1280A-4R7Y or SRF1280A-6R8Y, provided the electrical characteristics align with the design requirements. Verify mechanical dimensions and thermal performance before substitution.
