Overview
The Bourns SRF1260A-4R7Y is a dual-winding shielded power inductor with an inductance of 4.7 µH and ±30% tolerance. It features a ferrite core and wirewound construction in a 5050 surface-mount package (12.5 x 12.5 x 6 mm). Key electrical parameters include a maximum DC current of 7 A, saturation current of 7 A, and DCR of 15.5 mΩ. The component operates between -40°C and +125°C, meets AEC-Q200 automotive standards, and exhibits a self-resonant frequency of 36.7 MHz.
Feature Summary
- Dual-winding configuration allows flexible series or parallel circuit integration
- Magnetically shielded design minimizes electromagnetic interference
- Automotive-grade reliability certified to AEC-Q200 standards
Applications
- Automotive electronic systems
- DC/DC converter circuits
- Power supply filtering
Procurement Notes
Verify the specific suffix against official Bourns documentation to confirm pinout and winding configuration. Ensure the procurement source provides valid traceability for AEC-Q200 compliance. Cross-reference the manufacturer part number with authorized distributor catalogs to prevent substitution errors during assembly.
Selection Notes
Select this component for applications requiring high current handling in compact spaces. The dual-winding architecture supports transformer or coupled-inductor topologies. Verify that the 7 A saturation limit aligns with peak load requirements. Confirm PCB footprint compatibility with the 5050 package dimensions before finalizing the design.
Part Context
This component belongs to the SRF1260A series of shielded power inductors manufactured by Bourns. The series is designed for high-current applications, offering magnetic shielding to reduce radiation. The SRF1260A-4R7Y specifically utilizes a 4.7 µH value within the broader range of available inductances for this form factor.
Replacement Considerations
Consult official Bourns cross-reference lists for verified substitutes. Generic equivalents may not match the dual-winding configuration or AEC-Q200 certification.
