Fixed Inductors Procurement Notes

Verify the specific suffix '23L' against official Murata documentation to confirm pinout and packaging details. Ensure the selected variant matches the required 530 mA current rating and 260 mΩ DCR specifications for your circuit design. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Fixed Inductors Selection Notes

Select this component when an unshielded inductor is acceptable to minimize size and cost while maintaining 3.3 µH inductance. Consider the 530 mA saturation current limit and 260 mΩ DC resistance for efficiency requirements. Verify that the 1.70 mm maximum height fits within the board's mechanical constraints and that the 1210 metric footprint aligns with the PCB layout.

Fixed Inductors Part Context

This part belongs to the Murata LQH32DN series of RF and power inductors. These components are designed for general-purpose use in electronic circuits requiring fixed inductance values. The series offers various inductance options within the 1210 case size, catering to different current and resistance needs in compact designs.

Fixed Inductors Replacement Considerations

Direct substitutes include other Murata LQH32DN series parts with identical electrical parameters and footprint, such as LQH32DN3R3K23L if tighter tolerance is needed. External manufacturers may offer compatible 1210 unshielded drum core inductors, but verification of current ratings and DCR is essential.
