Fixed Inductors Procurement Notes

Verify the specific manufacturer part number against official Pulse Electronics documentation to ensure accuracy. Confirm that the unshielded configuration aligns with your electromagnetic interference requirements. Check for RoHS compliance status and moisture sensitivity levels relevant to your assembly process. Ensure the reel packaging quantity matches your production needs.

Fixed Inductors Selection Notes

Select this component when a compact, unshielded inductor is required for high-current power stages. The 12.8 x 12.8 mm footprint offers a balance between size and current capacity. Consider the 40 mΩ DCR for efficiency calculations. Verify that the lack of shielding does not interfere with nearby sensitive components due to potential magnetic field exposure.

Fixed Inductors Part Context

This component belongs to the PA4309 series of surface-mount power inductors from Pulse Electronics. The series is characterized by its drum core construction and unshielded design, suitable for applications where space is constrained but high current ratings are essential. It falls under the broader category of fixed inductors used in power management.

Fixed Inductors Replacement Considerations

Direct substitutes include other PA4309 series variants with different inductance values, such as PA4309.473NLT or PA4309.682NLT, provided the electrical parameters match the circuit requirements. Cross-referencing with similar unshielded drum-core inductors from other manufacturers requires careful verification of current ratings and physical dimensions.
