LQW04AN3N0D00D

Fixed Inductors Overview

The Murata LQW04AN3N0D00D is a surface-mount RF inductor from the LQW series, designed for high-frequency applications. It features an unshielded wirewound construction with a ferrite core, housed in a compact 03015 (0804 metric) package measuring 0.8 mm in length, 0.4 mm in width, and 0.4 mm in height. The component provides a nominal inductance of 3 nH with a tolerance of ±0.5 nH. It supports a maximum DC current of 620 mA and maintains a maximum DC resistance of 70 mΩ. The device operates within a temperature range of -55°C to +125°C and exhibits a self-resonant frequency of 20 GHz.

Fixed Inductors Feature Summary

• Unshielded wirewound design suitable for non-magnetic environments
• Compact 03015 footprint optimized for space-constrained PCB layouts
• High self-resonant frequency enabling effective RF signal handling

Fixed Inductors Applications

• RF circuit impedance matching networks
• High-frequency filtering stages
• Broadband amplifier biasing circuits

Fixed Inductors Procurement Notes

Verify the specific inductance value and tolerance against project requirements before ordering. Confirm that the 03015 package dimensions align with the target PCB land pattern. Ensure the maximum DC current rating of 620 mA meets the operational load conditions. Check RoHS compliance status if environmental regulations apply to the final assembly.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 3 nH is required for RF paths. The unshielded structure minimizes size but may require layout considerations regarding magnetic coupling. Compare the Q factor at the operating frequency against alternative models if selectivity is critical. Ensure the 70 mΩ DC resistance does not introduce excessive loss in power-sensitive designs.

Fixed Inductors Part Context

This part belongs to the Murata LQW series of fixed inductors, which are engineered for general-purpose RF and microwave applications. The series offers various inductance values in standard small-footprint packages. The LQW04AN variant specifically utilizes wirewound technology to achieve stable performance across wide frequency ranges while maintaining a low profile for modern surface-mount manufacturing processes.

Fixed Inductors Replacement Considerations

Direct substitutes include other Murata LQW04AN parts with identical 3 nH inductance, such as LQW04AN3N3D00D, though tolerance and current ratings may differ. Cross-manufacturer equivalents must match the 03015 package, 3 nH value, and unshielded wirewound characteristics to ensure mechanical and electrical compatibility.
