LQH43MN5R6K03L

Fixed Inductors Overview

The Murata LQH43MN5R6K03L is an unshielded wirewound RF inductor designed for surface mount applications. It features a ferrite core and operates within the LQH series, housed in a standard 1812 (4532 metric) package measuring 4.5 mm in length, 3.2 mm in width, and 2.6 mm in height. The component provides an inductance of 5.6 µH with a tolerance of ±10%. It supports a maximum DC current of 500 mA and exhibits a maximum DC resistance of 470 mOhms. The self-resonant frequency is specified at 33 MHz, with a minimum quality factor of 30. It functions reliably across a temperature range from -40°C to +85°C.

Fixed Inductors Feature Summary

Fixed Inductors Procurement Notes

Verify the specific ordering suffix and manufacturer part number against official Murata documentation to ensure correct tolerance and packaging specifications. Confirm that the required operating temperature range aligns with the component's rated limits before finalizing procurement orders. Cross-reference datasheet parameters with system requirements to validate electrical compatibility.

Fixed Inductors Selection Notes

Select this component when a 5.6 µH inductance value is required in an unshielded 1812 footprint. Ensure the application current does not exceed 500 mA to maintain reliability. Consider the 33 MHz self-resonant frequency limit for high-frequency circuit designs. Verify PCB space constraints match the 4.5 x 3.2 mm dimensions.

Fixed Inductors Part Context

This part belongs to the Murata LQH series of fixed inductors, which are widely used in consumer electronics and industrial applications. The LQH43MN5R6K03L specifically targets general-purpose RF and power filtering needs. Its unshielded design allows for flexible layout options while maintaining cost-effectiveness for mass production environments.

Fixed Inductors Replacement Considerations

Direct substitutes include the LQH43MN5R6M03L, which shares identical electrical characteristics but offers a wider ±20% tolerance. Designers should verify pinout compatibility and thermal performance when transitioning between these variants.
