Procurement Notes
Verify the manufacturer part number against official API Delevan documentation to ensure authenticity. Confirm that the specific suffix matches the required electrical parameters, as variations may exist within the product line. Cross-reference specifications with the latest datasheet before integration into design or procurement processes.
Selection Notes
Select this component when a compact, high-current coupled inductor is required for surface-mount designs. Ensure the 15 µH parallel inductance and 2.3 A current rating align with the circuit requirements. Verify that the 13.5 mm footprint fits the available board space and thermal constraints.
Part Context
This component belongs to the 4448R series of coupled inductors manufactured by API Delevan. The series is characterized by molded toroidal cores designed for high-current applications. These components are typically used in power management systems where space efficiency and magnetic coupling are critical.
Replacement Considerations
Check for direct substitutes within the 4448R series, such as the 4448R-134L, which shares similar packaging but different electrical characteristics. Ensure any replacement maintains the required inductance, current rating, and physical dimensions.
