4448-110M

Overview

The Delevan 4448-110M is a coupled power inductor from the 4448/R series, designed for surface-mount technology. It features a molded toroidal construction with two coils. The parallel inductance is 5 µH with a 20% tolerance, while the series inductance is 20 µH. The component supports a maximum DC current of 4.4 A and has a maximum DC resistance of 14 mΩ. Its physical dimensions are 13.71 mm in length, 13.71 mm in width, and 7.87 mm in height.

Feature Summary

• Dual-coil coupled inductor architecture providing flexible circuit integration options
• Molded toroidal core design for structural stability and electromagnetic shielding
• High-current capability suitable for demanding power supply applications

Applications

• DC-DC converter input and output filtering
• Power distribution network decoupling
• Multi-phase interleaved power stages

Procurement Notes

Verify the specific manufacturer part number against official API Delevan documentation to ensure compatibility with your design requirements. Confirm that the RoHS status aligns with your regulatory compliance needs, as indicated in the product specifications. Ensure that the surface-mount package dimensions fit within your PCB layout constraints before finalizing procurement decisions.

Selection Notes

Select this component when a coupled inductor with high current handling is required for space-constrained designs. The 14 mΩ DCR minimizes conduction losses at rated currents. Consider the 20% tolerance for ripple current calculations. The molded package offers robustness compared to wire-wound alternatives in high-vibration environments.

Part Context

This component belongs to the 4448/R series of coupled inductors manufactured by API Delevan. The series is characterized by its molded construction and suitability for high-current power electronics. It serves as a specialized passive component for managing energy storage and filtering in modern electronic systems.

Replacement Considerations

Check for equivalent parts in the 4448R series, such as the 4448R-110M, which may share identical electrical characteristics. Verify pinout compatibility and mechanical footprint alignment before substituting any alternative components.
