Overview
The Delevan 4448R-130L is a shielded surface-mount coupled inductor from the 4448/R series. It features a toroidal core construction with two coils, offering an inductance of 150 µH per coil at a 15% tolerance. The component supports high current applications with a maximum DC current rating of 7 A and a maximum DC resistance of 0.372 Ohms. Its physical dimensions are 13.71 mm in length and width, with a height of 7.87 mm. Designed for PCB mounting via SMD/SMT terminations, it is supplied in reel packaging.
Feature Summary
- Dual-coil toroidal architecture enabling flexible circuit configurations
- Shielded design to minimize electromagnetic interference
- High current handling capability suitable for power filtering
Applications
- DC-DC converter input/output filtering
- Power supply noise suppression
- Signal line coupling circuits
Procurement Notes
Verify the specific suffix 'L' against official datasheets to confirm lead-free compliance and termination material specifications. Confirm that the 0.372 Ohm DC resistance value aligns with the latest manufacturer revision. Ensure the reel quantity matches project requirements as factory pack quantities may vary by region.
Selection Notes
Select this component when dual independent or coupled inductance is required in a compact footprint. The 150 µH value and 7 A rating make it suitable for moderate-power switching applications. Compare thermal performance and saturation characteristics against alternative series if higher current density is needed.
Part Context
This part belongs to the 4448/R series of shielded surface-mount inductors manufactured by API Delevan. The series is characterized by its toroidal geometry and robust construction for high-reliability environments. It sits within the broader category of power inductors designed for efficient space-constrained electronic assemblies.
Replacement Considerations
Check for direct substitutes within the 4448R series with different inductance values. Verify mechanical compatibility with existing footprints before considering cross-brand alternatives.
