4448-108M

Overview

The Delevan 4448-108M is a coupled inductor from the 4448/R series, designed for surface mount technology (SMT) applications. It features a toroidal core construction with molded packaging. The component provides an inductance of 2 µH when connected in parallel and 8 µH in series, with a tolerance of ±20%. It supports a maximum DC current of 5.9 A and exhibits a maximum DC resistance of 7 mΩ. The physical dimensions are 13.71 mm in length, 13.71 mm in width, and 7.87 mm in height. It utilizes SMD/SMT termination types and is supplied in reel packaging.

Feature Summary

• Dual-coil configuration offering selectable parallel or series inductance values
• High-current capability with low DC resistance for efficient power handling
• Molded surface-mount design ensuring mechanical stability and compact footprint

Applications

• Multi-phase DC-DC converter output filtering
• Power supply input/output ripple reduction
• EMI suppression in high-current digital circuits

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm lead times and minimum order quantities directly with authorized distributors, as stock levels fluctuate. Ensure the specific suffix matches required tape-and-reel specifications for automated assembly processes.

Selection Notes

Select this component when dual-inductor functionality is required in a single package to save board space. The 2 µH parallel rating suits moderate current applications up to 5.9 A. Consider thermal management due to the molded package's heat dissipation characteristics under continuous load conditions.

Part Context
