Procurement Notes
Verify RoHS compliance status as documentation indicates non-compliance. Confirm lead times and minimum order quantities directly with authorized distributors or the manufacturer, as stock levels fluctuate. Ensure the specific suffix matches the required electrical parameters before ordering.
Selection Notes
Select this component when high current capacity and low DC resistance are critical for power efficiency. The 50 uH inductance value suits specific filtering requirements. Verify that the 13.71 x 13.71 mm footprint fits the PCB layout constraints and that the thermal performance meets the operating environment standards.
Part Context
This part belongs to the 4448/R series of surface mount power inductors manufactured by API Delevan. The series offers various inductance values tailored for different current ratings. The 4448-24L specifically targets high-current applications within this lineup, utilizing a robust molded construction to withstand mechanical stress and thermal cycling.
Replacement Considerations
Cross-reference with other 4448 series variants such as 4448-124L for similar form factors but different electrical characteristics. Ensure any substitute matches the 50 uH inductance, 50 A current rating, and physical dimensions to maintain board compatibility.
