SRF1260A-100M

Overview

The Bourns SRF1260A-100M is a dual-winding shielded power inductor array with a nominal inductance of 10 µH and ±20% tolerance. It features a ferrite core and wirewound construction within a 12.5 mm x 12.5 mm x 6.2 mm surface-mount package. The component supports parallel connection with a maximum DC current of 7.17 A and series connection with a maximum DC current of 3.59 A. It operates within a temperature range of -40°C to +125°C and meets AEC-Q200 automotive qualification standards.

Feature Summary

• Dual-winding architecture enabling flexible circuit configurations
• Shielded design to minimize electromagnetic interference
• Automotive-grade reliability certification

Applications

• Automotive power supply circuits
• Parallel inductor configurations for high-current applications
• Series inductor configurations for voltage boosting

Procurement Notes

Verify the specific suffix 'A' against the datasheet to confirm it denotes the automotive-grade variant, as standard SRF1260 parts may lack this qualification. Ensure the ordering code matches the required packaging format, such as cut tape or reel, directly from the manufacturer's official documentation before finalizing procurement.

Selection Notes

Select this component when dual-coil flexibility is required for space-constrained designs. Evaluate the saturation current requirements carefully, noting the significant difference between parallel (7.17 A) and series (3.59 A) operational modes. Confirm that the 12.5 mm footprint fits the PCB layout constraints and that the operating temperature range aligns with the system environment.

Part Context

This part belongs to the SRF1260A series of dual-winding shielded power inductors manufactured by Bourns. The series is designed for high-current applications requiring compact footprints. The 'A' suffix typically indicates automotive qualification, distinguishing it from the standard SRF1260 series which may not meet AEC-Q200 standards.

Replacement Considerations

Direct substitutes include other Bourns dual-winding inductors in the SRF1260 series with matching inductance values. Verify pinout compatibility and physical dimensions when considering cross-brand alternatives to ensure seamless integration into existing automotive power architectures.
