4448-04M

Overview

The Delevan 4448-04M is a coupled inductor array featuring two coils with a parallel inductance of 680 nH and a series inductance of 3 uH. It exhibits a tolerance of 20% and a maximum DC resistance of 6 mOhms. The component supports a maximum DC current of 7.2 A and utilizes an SMD/SMT termination style for PCB mounting. Its physical dimensions are 13.71 mm in length, 13.71 mm in width, and 7.87 mm in height. The unit belongs to the 4448/R series and is classified as a toroidal power inductor.

Feature Summary

Dual-coil configuration allowing flexible series or parallel circuit integration
High-current capability designed for demanding power applications
Molded surface-mount construction for robust mechanical stability

Applications

Power supply input filtering stages
DC-DC converter output smoothing
Signal integrity enhancement in mixed-signal circuits

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm package availability options such as cut tape or reel formats with the supplier. Ensure the specific manufacturing date code aligns with project requirements. Cross-reference the manufacturer part number API Delevan 4448-04M to ensure accurate sourcing from authorized channels. Check for any obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a compact dual-inductor solution is required for high-current paths. The low DC resistance minimizes power loss during operation. Consider the 680 nH parallel value for fast transient response needs. Evaluate the 7.2 A rating against peak load currents to prevent saturation. The standard SMD footprint facilitates automated assembly processes.

Part Context

This component is part of the 4448/R series manufactured by API Delevan. It falls under the category of coupled inductors within the broader inductors and chokes classification. The series is known for providing integrated magnetic solutions that save board space compared to discrete components.
