MHQ1005P3N7ST000

Fixed Inductors Overview

The MHQ1005P3N7ST000 is a fixed surface-mount multilayer RF inductor from TDK's MHQ-P series. It features a ceramic core and an unshielded design within a 0402 (1006 metric) package measuring 1.0mm x 0.6mm x 0.6mm. The component provides an inductance of 3.7 nH with a tolerance of ±0.3 nH. It supports a maximum DC current of 900 mA and has a maximum DC resistance of 100 mΩ. The self-resonant frequency reaches 6 GHz, with a minimum quality factor of 23 at 250 MHz. Operating temperatures range from -55°C to +125°C.

Fixed Inductors Feature Summary

• High-frequency performance optimized for RF applications with a self-resonant frequency up to 6 GHz
• Super-high Q factor characteristics ensuring efficient signal transmission in compact circuits
• Robust construction using ceramic core material suitable for demanding thermal environments

Fixed Inductors Applications

• RF matching networks in wireless communication modules
• Impedance matching circuits in mobile devices
• Filtering components in high-frequency signal processing systems

Fixed Inductors Procurement Notes

Verify the specific package dimensions against the official datasheet, as the 0402 variant may differ from standard 0402 sizes. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure soldering profiles align with TDK guidelines for multilayer ceramic inductors to prevent mechanical stress or parameter drift during reflow processes.

Fixed Inductors Selection Notes

Select this component when space constraints require a 0402 footprint but higher current handling than standard variants allows. Consider the 100 mΩ DCR limit for power loss calculations. Evaluate the 6 GHz self-resonant frequency to ensure operation remains below the resonance point for intended filter or matching network functions. Compare against similar MHQ-P series parts for alternative inductance values if system requirements change.

Fixed Inductors Part Context

This part belongs to TDK's MHQ-P series, which specializes in super-high Q multilayer RF inductors. The series is designed for miniaturization while maintaining electrical stability at radio frequencies. These components are widely used in consumer electronics requiring small form factors and reliable high-frequency behavior.

Fixed Inductors Replacement Considerations

Direct substitutes include other MHQ1005P series inductors with identical 3.7 nH inductance and compatible package dimensions. Verify that alternative parts maintain the same 900 mA current rating and 100 mΩ DCR specifications to ensure circuit performance parity.
