Overview
The Delevan 4448R-30L is a coupled inductor from the 4448/R series, designed for surface mount technology (SMT) applications. It features a toroidal core structure with two coils. The component provides an inductance of 150 µH when connected in parallel and 600 µH when connected in series. It has a maximum DC resistance of 696 mΩ in the parallel configuration. The device supports a maximum DC current of 640 mA in parallel mode and 320 mA in series mode. It utilizes SMD/SMT termination styles for PCB mounting.
Feature Summary
- Dual-coil toroidal architecture for coupled inductor functionality
- Surface mount design optimized for automated PCB assembly
- Configurable inductance via series or parallel coil connection
Applications
- Power supply filtering circuits requiring coupled inductance
- DC-DC converter input/output stages
- Signal processing arrays needing magnetic coupling
Procurement Notes
Verify the specific suffix 'L' against the manufacturer's latest datasheet to confirm pinout and tolerance specifications. Ensure the procurement channel sources directly from API Delevan or authorized distributors to guarantee component authenticity. Cross-reference the RoHS status and lead times with official supplier documentation prior to finalizing orders.
Selection Notes
Select this component when a dual-coil toroidal inductor is required for space-constrained SMT designs. Evaluate the 696 mΩ DCR limit against the circuit's power loss requirements. Confirm that the 640 mA parallel current rating meets the operational load demands. Consider the 150 µH parallel inductance value for filter cutoff frequency calculations.
Part Context
This part belongs to the Delevan 4448/R series of coupled inductors. The series is characterized by toroidal cores and SMT packaging. These components are engineered for high-current applications where magnetic coupling between coils is necessary. The 4448R-30L specifically offers 150 µH parallel inductance.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided source data. Verify compatibility with existing footprints if considering alternative manufacturers.
