Procurement Notes
Verify the manufacturer part number against official API Delevan documentation to ensure authenticity. Confirm that the specific suffix 'L' matches the required specifications for your design. Check RoHS status and lead times directly with authorized distributors or the manufacturer. Ensure storage conditions comply with moisture sensitivity levels if applicable. Validate compatibility with your assembly process before finalizing orders.
Selection Notes
Select this component when a 300 µH coupled inductor with low current handling is required. Consider the 1 Ohm DC resistance impact on efficiency. Compare with other 4448 series variants like 4448-112M for higher current needs. Ensure the 13.71 mm footprint fits the PCB layout constraints. Evaluate thermal performance under the 540 mA maximum current rating.
Part Context
This component belongs to the Delevan 4448/R series of power inductors. These parts are characterized by their toroidal core structure and molded construction. The series offers various inductance values tailored for different power management applications. The 4448R-34L specifically targets applications requiring moderate inductance with compact surface-mount packaging.
Replacement Considerations
Direct substitutes may include other 4448 series models with similar electrical characteristics. Verify pinout and mechanical dimensions before substitution. Consult API Delevan for recommended alternatives if exact matches are unavailable.
