SRF1260-4R7Y

Overview

The Bourns SRF1260-4R7Y is a dual-winding shielded power inductor array with a ferrite core and wirewound construction. It features an inductance of 4.7 µH per coil with ±30% tolerance, measuring 12.5 mm x 12.5 mm x 6.0 mm. The component supports a maximum DC current of 7.18 A and a saturation current of 9.71 A, with a maximum DC resistance of 13.7 mΩ. It operates between -40°C and +125°C, offering a minimum Q of 9 at 7.96 MHz and a self-resonant frequency of 60 MHz.

Feature Summary

• Dual-winding configuration allows series or parallel connection for flexible circuit design
• Magnetic shielding reduces electromagnetic interference and radiation
• Ferrite core and wirewound technology ensure stable performance under high current loads

Applications

• Automotive electronic systems requiring AEC-Q200 compliance
• DC/DC converter circuits for power management
• High-density power supply designs

Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's latest datasheet to confirm packaging details and exact electrical tolerances. Confirm RoHS compliance status directly with the supplier documentation before integration into production schedules.

Selection Notes

Select this component when dual isolated windings are required within a compact footprint. The 12.5 mm square package provides higher current handling than smaller surface-mount alternatives while maintaining low profile dimensions suitable for space-constrained automotive and industrial boards.

Part Context

This part belongs to the SRF1260 series of dual-winding shielded power inductors manufactured by Bourns Inc. The series is designed for applications demanding high current capacity and magnetic shielding in a standardized surface-mount form factor.

Replacement Considerations

Cross-reference with SRR1260A-4R7Y for single-winding automotive-grade alternatives. Verify pinout compatibility and thermal characteristics before substituting with other coupled inductor arrays from different manufacturers.
