Overview
The Delevan 4448-10M is a surface-mount coupled inductor from the 4448/R series, designed for high-current applications. It features a molded SMT construction with a toroidal core type and PCB mount installation style. The component has an inductance of 5 µH with a 20% tolerance and a maximum DC resistance of 0.027 ohms. Its physical dimensions are 13.71 mm in length, 13.71 mm in width, and 7.87 mm in height. The device is supplied in a tape and reel packaging format.
Feature Summary
- High current capability suitable for demanding power circuits
- Molded surface mount technology for automated assembly
- Toroidal core design for efficient magnetic coupling
Applications
- Power supply input filtering
- DC-DC converter stages
- EMI suppression in compact electronics
Procurement Notes
Verify the specific suffix (e.g., M) against the manufacturer's latest datasheet to ensure correct tolerance and termination specifications. Confirm RoHS compliance status as indicated in official documentation before integration into regulated assemblies. Check for any recent lifecycle changes or obsolescence notices directly from API Delevan to avoid supply chain disruptions during production.
Selection Notes
Select this component when a compact, high-current coupled inductor is required for space-constrained designs. The 5 µH value and low DCR make it suitable for applications needing significant ripple current handling. Ensure the operating temperature range and saturation current requirements align with the system's thermal and electrical constraints before finalizing the bill of materials.
Part Context
This part belongs to the Delevan 4448/R series of surface-mount power inductors. The series is characterized by its molded construction and high-current performance. Similar parts in the lineup include the 4448-104M and 4448-112M, which offer different inductance values while maintaining the same footprint and mounting style for design flexibility.
Replacement Considerations
Direct substitutes may include other 4448 series variants with adjusted inductance if electrical parameters differ. Cross-reference with API Delevan's official replacement guide for equivalent components that match the 13.71 x 13.71 mm footprint and toroidal structure.
