SRF1260A-3R3Y

Overview

The Bourns SRF1260A-3R3Y is a shielded dual-coil inductor array with a nominal inductance of 3.3 µH per coil at ±30% tolerance. It measures 12.50 mm x 12.50 mm x 6.20 mm and operates from -40°C to +125°C. Parallel connection yields 3.3 µH, 9.26 A rated current, 12.7 A saturation, and 10.1 mΩ DCR. Series connection yields 13.2 µH, 4.63 A rated current, 6.35 A saturation, and 37.2 mΩ DCR.

Feature Summary

• Dual-winding configuration allows flexible series or parallel circuit integration
• Shielded construction minimizes electromagnetic interference
• AEC-Q200 qualification ensures automotive reliability

Applications

• Automotive power distribution networks
• DC-DC converter input/output filtering
• High-current point-of-load regulation

Procurement Notes

Verify the specific suffix against official documentation to confirm exact packaging and reel specifications. Confirm RoHS compliance status for your region. Ensure the ordering quantity matches the manufacturer's standard shipping unit requirements to avoid handling fees or order adjustments.

Selection Notes

Select this component when high current density and low DC resistance are required in a compact surface-mount footprint. The dual-coil design supports interleaved phase configurations to reduce ripple current. Verify that the thermal management capabilities of the PCB can handle the specified saturation currents without exceeding temperature limits.

Part Context

This part belongs to the SRF1260A series of shielded power inductor arrays. The series provides various inductance values within the same 12.50 mm x 12.50 mm package. It is designed for applications requiring robust performance under high load conditions.

Replacement Considerations

Check the SRF1260A-6R8Y for higher inductance needs. Verify pinout compatibility before substituting with other dual-coil arrays.
