Overview
The Delevan 4448R-102M is a coupled inductor from the 4448/R series, designed for surface mount technology. It features a toroidal core construction with two coils. The component provides an inductance of 0.47 uH (470 nH) per coil with a tolerance of 20%. In parallel configuration, the inductance is 0.47 uH, while in series it reaches 2 uH. It supports a maximum DC current of 7.9 A and has a maximum DC resistance of 4 mOhms per coil. The 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 applications
- Toroidal core design for efficient magnetic coupling
- Surface mount termination for automated PCB assembly
Applications
- Power supply circuits requiring coupled inductance
- DC-DC converter topologies
- Signal filtering in high-current paths
Procurement Notes
Verify the manufacturer designation carefully, as API Delevan and Delevan are associated with this part number. Confirm RoHS compliance status through official documentation, as sources vary. Ensure the specific suffix matches the required electrical parameters. Cross-reference with authorized distributors to confirm current availability and lead times before finalizing procurement plans.
Selection Notes
Select this component when a compact, high-current coupled inductor is required for SMT processes. The 4 mOhm DCR minimizes conduction losses at high currents. Compare the 7.9 A rating against peak load requirements. Consider the 13.71 mm footprint for board space constraints. Verify thermal management needs given the high current handling capability.
Part Context
This component belongs to the 4448/R series of power inductors manufactured by API Delevan. The series is characterized by molded or toroidal constructions optimized for high current density. These components are typically used in power electronics where size and efficiency are critical. The 4448R-102M specifically utilizes a toroidal geometry for its magnetic properties.
Replacement Considerations
Check for direct substitutes within the 4448R series with similar inductance and current ratings. Verify pinout compatibility if replacing in existing designs. Ensure the replacement maintains the same package dimensions and mounting style.
