Fixed Inductors Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to ensure correct packaging configuration. Confirm that the selected variant matches the required inductance value and current rating specifications for the target application circuit. Cross-reference the manufacturer part number with distributor codes to prevent procurement errors during sourcing.

Fixed Inductors Selection Notes

Select this component when an unshielded inductor is acceptable to minimize electromagnetic interference coupling concerns while requiring high saturation current. Ensure the PCB footprint accommodates the 12.80 mm x 12.80 mm base and 7.00 mm height. Verify thermal management strategies align with the 125°C operating limit under full load conditions.

Fixed Inductors Part Context

This component belongs to the PA4309.XXXNL series of fixed power inductors from Pulse Electronics. The series offers various inductance values within a standardized non-standard SMD footprint. It serves as a passive energy storage element in switching regulator topologies, distinguishing itself through its wirewound construction and unshielded magnetic architecture.

Fixed Inductors Replacement Considerations

Direct substitutes include other PA4309 series variants with matching 22 µH inductance and similar current ratings. Alternative manufacturers offering comparable 12.80 mm x 12.80 mm unshielded wirewound inductors may be considered if pin compatibility and electrical parameters align precisely.
