4448R-24L

Overview

The Delevan 4448R-24L is a coupled inductor from the 4448/R series, designed for high-current surface-mount applications. It features a toroidal construction with molded shielding. Key electrical specifications include an inductance of 50 µH with a 15% tolerance and a maximum DC resistance of 0.202 Ω. The component supports a maximum DC current of 7.9 A. 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

High-current capability suitable for demanding power stages
Molded shielded toroidal design for EMI reduction
Surface-mount form factor for automated assembly

Applications

DC-DC converter output filtering
Power supply input stages
Point-of-load regulation circuits

Procurement Notes

Verify the specific manufacturer designation, as sources list both API Delevan and generic Delevan branding. Confirm RoHS compliance status, as some related series parts are marked non-compliant. Ensure the ordering suffix matches the required tape-and-reel quantity. Cross-reference the exact DCR and saturation current values against the latest official datasheet to avoid discrepancies between distributor listings and manufacturer specifications.

Selection Notes

Select this component when high current handling is required in a compact footprint. The 50 µH value and low DCR make it suitable for efficient power conversion. Compare against the 4448-112M or 4448-104M if different inductance or current ratings are needed. Ensure the PCB layout accommodates the 13.71 x 13.71 mm package size and thermal requirements associated with high-current operation.

Part Context

This part belongs to the 4448/R series of coupled inductors manufactured by API Delevan. The series is characterized by molded toroidal cores designed for high-current applications. Other variants in the family include the 4448-104M and 4448-112M, which offer different inductance and current ratings while maintaining similar physical footprints.
