Overview
The Delevan 4448-20L is a coupled inductor from the 4448/R series, designed for high-current surface-mount applications. It features a molded construction with two coils, offering an inductance of 25 uH and a tolerance of 15%. The component has a maximum DC current rating and a maximum DC resistance of 0.116 ohms. It utilizes SMD/SMT termination types for PCB mounting.
Feature Summary
- High-current molded surface-mount design
- Dual-coil coupled inductor configuration
- RoHS non-compliant due to lead content
Applications
- Power supply circuits requiring coupled inductance
- DC-DC converter topologies
- High-current signal filtering
Procurement Notes
Verify RoHS compliance status prior to integration, as this specific part number is identified as non-compliant due to lead presence. Confirm that the manufacturing source is API Delevan or authorized distributors. Ensure the procurement channel provides valid traceability documentation for the component's material composition and origin to meet regulatory requirements for restricted substances.
Selection Notes
Select this component when a 25 uH coupled inductor with high current handling capabilities is required for surface-mount assembly. Consider the physical dimensions and thermal characteristics associated with the molded package. Evaluate the 15% tolerance against circuit sensitivity requirements. Ensure the application environment accommodates the non-RoHS nature of the device if strict environmental regulations apply.
Part Context
This component belongs to the Delevan 4448/R series of coupled inductors. The series is characterized by high reliability and performance in power electronics. The 4448-20L specifically denotes the 25 uH variant within this lineup, sharing common packaging and mounting characteristics with other models in the family while differing in electrical specifications.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided data. Cross-reference with other 4448 series variants such as 4448-22L for similar form-factor needs, but verify electrical parameter compatibility independently.
