Overview
The Delevan 4448-22L is a coupled inductor from the 4448/R series, designed for surface-mount technology (SMT) applications. It features a molded high-current toroidal construction with two coils. The component provides an inductance of 33 µH per coil with a tolerance of 15%. The maximum DC current rating is specified at 3.5 A, while the maximum DC resistance is 0.166 ohms. The physical dimensions are 13.71 mm in length and width, with a height of 7.87 mm.
Feature Summary
- Molded high-current toroidal design for robust performance
- Surface-mount configuration for automated PCB assembly
- Dual-coil coupled inductor structure
Applications
- Power management circuits
- High-current filtering applications
- DC-DC converter stages
Procurement Notes
Verify the specific manufacturer part number against official API Delevan documentation to ensure compatibility with design requirements. Confirm that the RoHS status and moisture sensitivity level meet project specifications. Cross-reference electrical parameters such as inductance and DC resistance with the latest datasheet to avoid integration errors during procurement.
Selection Notes
Select this component when a dual-coil coupled inductor with high current handling capability is required for SMT processes. The 33 µH value and 3.5 A rating suit applications needing significant magnetic coupling and low resistance. Ensure the PCB footprint accommodates the 13.71 x 13.71 mm package size and 7.87 mm height constraints.
Part Context
The 4448-22L belongs to the 4448/R series of coupled inductors manufactured by API Delevan. This series is characterized by its molded toroidal construction, which supports high-current operation in a compact surface-mount form factor. The component is categorized under power inductors and is distinct from general-purpose RF or signal inductors due to its specific magnetic coupling and current ratings.
Replacement Considerations
Consult official API Delevan substitution guides for verified equivalents. Generic cross-references may not match the specific coupled inductance and current characteristics required.
