SRF1260A-681M

Overview

The Bourns SRF1260A-681M is a dual-winding shielded power inductor array designed for surface mount applications. It features an inductance of 680 µH when connected in parallel and 2.72 mH in series, with a tolerance of ±20%. The component has a maximum DC resistance of 1.212 Ω in parallel configuration and operates within a temperature range of -40°C to +125°C. It meets AEC-Q200 automotive standards and utilizes a 12.5mm x 12.5mm x 6.20mm package.

Feature Summary

• Dual-winding magnetic shielding reduces electromagnetic interference
• Automotive-grade reliability compliant with AEC-Q200 standards
• High saturation current capability for stable performance under load

Applications

• Automotive power supply circuits
• DC-DC converter input/output filtering
• On-board charging systems

Procurement Notes

Verify the specific suffix '681M' confirms the 680 µH value and ±20% tolerance. Ensure the ordering part number matches the required packaging format, such as cut tape or reel, as availability varies by distributor. Confirm RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when space-constrained designs require coupled inductors with high current handling. The 1260A footprint supports significant thermal dissipation. Verify that the parallel inductance of 680 µH aligns with the target filter frequency and that the series configuration meets isolation requirements if applicable.
