SRF1260-680M

Overview

The Bourns SRF1260-680M is a shielded coupled inductor array featuring two coils with an inductance of 68 µH when connected in parallel and 272 µH in series. It utilizes a ferrite core and wirewound construction within a surface-mount 1260 package measuring 12.5 x 12.5 x 6 mm. The component supports a maximum DC current of 2.7 A and has a maximum DC resistance of 444 mΩ. It operates between -40°C and +125°C with a ±20% tolerance.

Feature Summary

• Dual-coil architecture providing flexible series or parallel connection options
• Shielded design to minimize electromagnetic interference
• Ferrite core construction for stable magnetic performance

Applications

• Power supply filtering circuits
• DC-DC converter input/output stages
• Signal conditioning networks

Procurement Notes

Verify the specific datasheet version for precise electrical tolerances and thermal characteristics before integration. Confirm that the 1260 footprint dimensions align with your PCB layout constraints. Ensure the selected mounting method supports the specified operating temperature range of -40°C to +125°C. Cross-reference the manufacturer's part number to avoid confusion with similar series components.

Selection Notes

Choose this component when dual-inductor functionality is required in a compact surface-mount form factor. The shielded structure makes it suitable for noise-sensitive environments. Evaluate the 2.7 A current rating against peak load requirements. Consider the 444 mΩ DC resistance impact on overall circuit efficiency during continuous operation.

Part Context

This part belongs to the Bourns SRF1260 series of coupled inductors. These components are designed for high-density power electronics applications requiring reliable magnetic coupling. The series offers various inductance values while maintaining consistent physical dimensions for standardized board designs.

Replacement Considerations

Direct substitutes must match the 1260 package size, 68 µH parallel inductance, and 2.7 A current rating. Verify compatibility of the ferrite core material and shielding effectiveness. Ensure the replacement maintains the same thermal performance limits.
