4448R-12M

Overview

The Delevan 4448R-12M is a surface-mount coupled inductor array featuring two coils with an inductance of 8 µH and a tolerance of 20%. It exhibits a maximum DC resistance of 0.033 ohms per coil, supporting high-current molded SMT applications. The component utilizes a toroidal core construction within a rectangular package measuring 13.71 mm in length and width, with a height of 7.87 mm.

Feature Summary

Dual-coil coupled inductor array configuration
High-current molded surface mount design
Toroidal core construction for magnetic efficiency

Applications

Power supply input filtering
DC-DC converter stages
Data line noise suppression

Procurement Notes

Verify the specific suffix designation against official API Delevan documentation to confirm exact electrical tolerances and lead-free compliance status. Ensure the ordering quantity aligns with manufacturer packaging constraints, as factory pack quantities may vary between standard reels and alternative configurations. Cross-reference the Mouser part number 807-4448R-12M for current availability and updated datasheet revisions prior to final procurement decisions.

Selection Notes

Select this component for circuits requiring compact dual-inductor solutions with high current handling capabilities. The 8 µH value suits intermediate frequency filtering needs. Verify that the 0.033 ohm DC resistance meets thermal management requirements for the target application's continuous current load. Confirm that the 7.87 mm profile fits within the mechanical envelope constraints of the printed circuit board assembly.
