SRF1260-100M

Overview

The Bourns SRF1260-100M is a dual-winding shielded power inductor from the SRF1260 series, designed for surface-mount applications. It features a ferrite core and measures 12.5 mm x 12.5 mm x 6 mm. The component provides an inductance of 10 µH with ±20% tolerance in parallel connection, or 40 µH in series configuration. It supports a maximum RMS current of 5.35 A (parallel) and 2.67 A (series), with corresponding saturation currents of 7.17 A and 3.59 A. DC resistance is 24.6 mΩ (parallel) and 93.4 mΩ (series). Operating temperature ranges from -40°C to +125°C.

Feature Summary

• Dual-winding architecture enabling flexible series or parallel circuit configurations
• Magnetically shielded construction to minimize electromagnetic interference
• Ferrite core design optimized for high-frequency power applications

Applications

• DC-DC converter output filtering
• Power supply input stages
• Point-of-load regulation circuits

Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm electrical characteristics and packaging options. Ensure compatibility with RoHS3 standards if required by your assembly process. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm lead times and minimum order quantities directly with suppliers before finalizing procurement plans.

Selection Notes

Select this component when dual independent windings are required within a single compact footprint. The shielded design suits environments sensitive to magnetic coupling. Evaluate thermal performance at the target operating current to ensure the 125°C rating is not exceeded. Consider series versus parallel connectivity based on system voltage and current requirements.

Part Context

This part belongs to the SRF1260 series of dual-winding shielded power inductors manufactured by Bourns Inc. The series offers various inductance values within a standardized 1260 package size, providing designers with consistent mechanical dimensions while allowing flexibility in electrical specifications for diverse power management needs.

Replacement Considerations

Direct substitutes include other SRF1260 series variants with different inductance values, such as SRF1260-101M. Verify that any replacement maintains the same physical dimensions, pinout, and shielding characteristics to ensure board compatibility.
