Overview
The Bourns SRF1260A-680M is a shielded dual-coupled inductor array designed for surface mount applications. It features an inductance of 68 µH when connected in parallel and 272 µH in series, with a saturation current of 2.7 A. The component has a maximum DC resistance of 0.117 Ω per coil and operates within a temperature range of -40°C to +125°C. It utilizes a ferrite core material and meets AEC-Q200 automotive qualification standards.
Feature Summary
- Dual-coupled magnetic structure providing flexible series or parallel connectivity options
- Shielded design to minimize electromagnetic interference
- Automotive-grade reliability certified under AEC-Q200 standards
Applications
- Automotive power supply circuits
- DC-DC converter input/output filtering
- High-current coupled inductor arrays
Procurement Notes
Verify the specific suffix 'A' against the manufacturer's latest datasheet to confirm package and tolerance specifications. Ensure the application environment remains within the specified -40°C to +125°C operating range. Confirm that the 2.7 A saturation current rating aligns with peak load requirements to prevent performance degradation.
Selection Notes
Select this component for designs requiring coupled inductors with high current handling capabilities. The 12.5mm x 12.5mm footprint suits space-constrained automotive boards. Consider the 20% tolerance and ferrite core characteristics for ripple current management in switching regulator topologies.
Part Context
This part belongs to the Bourns SRF1260A series of high-current power inductors. The series is engineered for robust performance in demanding electronic environments, offering a wide inductance range from 0.47µH to 6500µH. The SRF1260A variant specifically targets automotive and industrial applications requiring reliable magnetic components.
Replacement Considerations
Cross-reference with other SRF1260A series variants for different inductance values. Verify pin compatibility and thermal characteristics before substituting with non-Bourns coupled inductor arrays.
