4448R-14L

Overview

The Delevan 4448R-14L is an unshielded coupled inductor array featuring two coils designed for surface-mount technology (SMT) PCB mounting. It provides a parallel inductance of 10 µH and a series inductance of 40 µH with a tolerance of ±15%. The component has a maximum DC resistance of 47 mΩ and operates within a temperature range of -55°C to 125°C.

Feature Summary

• Dual-coil configuration enabling flexible series or parallel circuit integration
• High-current molded SMT construction for robust board mounting
• Unshielded design suitable for applications where magnetic isolation is managed externally

Applications

• DC-DC converter input/output filtering
• Power supply ripple reduction circuits
• Multi-phase power distribution networks

Procurement Notes

Verify the specific suffix requirements against your Bill of Materials, as packaging variations may exist. Confirm RoHS compliance status directly with the manufacturer or authorized distributor, as regulatory certifications can change over time. Ensure the selected variant matches the required inductance tolerance and current rating for your specific thermal environment.

Selection Notes

Select this component when a compact dual-inductor solution is required for power stages. The 4448R series offers a standardized footprint that simplifies layout. Consider the unshielded nature of the device; ensure adequate spacing from sensitive signal traces to prevent electromagnetic interference coupling during operation.

Part Context

This part belongs to the 4448R series of coupled inductors from API Delevan. The series is characterized by toroidal core structures molded into surface-mount packages. These components are engineered for high-current applications, providing reliable performance in space-constrained power electronics designs requiring coupled magnetic elements.

Replacement Considerations

Cross-reference with other 4448R series variants such as 4448R-134L for different inductance values. Verify pinout compatibility and physical dimensions before substitution. Consult official Delevan documentation for equivalent parts with matching electrical characteristics and package outlines.
