4448-104M

Overview

The Delevan 4448-104M is a surface-mount coupled inductor from the 4448/R series, designed for high-current applications. It features a molded toroidal construction with SMD/SMT termination and PCB mount style. The component has an inductance of 680 nH in parallel configuration and 3 uH in series, with a 20% tolerance. It supports a maximum DC current of 7 A and exhibits a maximum DC resistance of 5 mOhms. Physical dimensions are 13.71 mm in length, 13.71 mm in width, and 7.87 mm in height.

Feature Summary

• High-current capability suitable for demanding power circuits
• Molded toroidal structure for robust mechanical integrity
• Dual winding configuration enabling flexible series or parallel operation

Applications

• Power supply input filtering
• DC-DC converter stages
• EMI suppression in data lines

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm lead times and factory pack quantities directly with API Delevan or authorized distributors. Ensure ordering suffixes match specific requirements without assuming functional changes. Validate physical footprint compatibility during integration planning.

Selection Notes

Select this component when high current handling and low DC resistance are critical. The 7 A rating and 5 mOhm resistance support efficient power delivery. Consider the 13.71 x 13.71 mm footprint for board space allocation. Evaluate thermal performance under continuous load conditions given the molded package design.
