SRF1260-151M

Overview

The Bourns SRF1260-151M is a dual-winding shielded power inductor from the SRF1260 series. It features an inductance of 150 µH per winding with ±20% tolerance. The component has a maximum DC current rating of 1.48 A and a maximum DC resistance of 0.972 Ω. It utilizes a ferrite core and wirewound structure within a 1260 surface-mount package measuring 12.5 x 12.5 x 6 mm. The device operates between -40°C and +125°C.

Feature Summary

• Dual-winding configuration supporting parallel or series circuit connections
• Magnetically shielded design to minimize electromagnetic interference
• Low-profile molded construction for space-constrained applications

Applications

• DC-DC converter circuits
• Power supply filtering
• Signal processing stages

Procurement Notes

Verify the specific part number suffix against official Bourns documentation to confirm electrical characteristics. Ensure the procurement channel provides valid manufacturer traceability. Confirm that the delivered components match the specified 1260 package dimensions and terminal type. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a dual-winding topology is required for coupled inductor applications. The 150 µH value suits moderate energy storage needs. Consider the 1.48 A current rating for load requirements. The shielded nature makes it suitable for sensitive environments where radiation must be limited compared to unshielded alternatives.

Part Context

This part belongs to the SRF1260 series of dual-winding shielded power inductors manufactured by Bourns Electronic Solutions. The series is characterized by its low-profile form factor and magnetic shielding, designed for high-reliability power electronics. It complements other Bourns magnetics products used in industrial and consumer electronic systems.

Replacement Considerations

Direct substitutes include other Bourns SRF1260 variants with different inductance values, such as SRF1260-680M. Cross-manufacturer replacements require matching the 1260 footprint, dual-winding capability, and similar electrical parameters.
