Procurement Notes
Verify the specific suffix (L vs M) to confirm lead-free compliance status, as API Delevan distinguishes between RoHS-compliant and non-compliant variants within this series. Confirm the exact inductance value against the latest manufacturer datasheet, as cross-references may list different values such as 8 µH or 68 µH for similar part numbers. Ensure the supplier provides official documentation to validate the active status and electrical parameters before integration.
Selection Notes
Select this component when a dual-coil coupled inductor with high current handling capability is required for space-constrained designs. The low profile and small footprint make it suitable for dense PCB layouts. Verify that the 68 µH inductance and 3.5 A current rating align with the circuit's power requirements. Consider the thermal performance associated with the molded construction and low DCR specification.
Part Context
The 4448 series represents a line of surface mount high-current power toroids manufactured by API Delevan. These components are engineered for robust performance in demanding electronic environments. The series offers various inductance options while maintaining consistent physical dimensions and mounting characteristics across the product family.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Cross-reference models such as 4448R-126L exist but require verification of identical electrical specifications and pinout compatibility before substitution.
