Fixed Inductors Procurement Notes

Verify the specific suffix against official Murata documentation to confirm package type and availability status. Ensure the ordering code matches the required reel or cut tape configuration. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when an unshielded inductor is required to minimize magnetic interference coupling in adjacent traces. The 4x4mm footprint offers a balance between current handling and board space. Verify that the 9 MHz self-resonant frequency aligns with the target application's operational bandwidth requirements.

Fixed Inductors Part Context

This part belongs to the Murata LQH44 series of fixed inductors. The series provides various inductance values within the same 1616 (4.0x4.0 mm) package outline. The PN suffix typically denotes standard packaging options available through major distributors.

Fixed Inductors Replacement Considerations

LQH44PN4R7MJ0L is listed as a discontinued alternative by some distributors, though it differs significantly in inductance value.
