LQH3NPN220MMRE

Fixed Inductors Overview

The Murata LQH3NPN220MMRE is a fixed power inductor from the LQH3NP series, designed for surface mount applications. It features a shielded wire-wound construction with a ferrite core, providing electromagnetic interference suppression. The component has an inductance of 22 µH with a tolerance of ±20%. It supports a maximum DC current of 750 mA and a saturation current of 390 mA. The DC resistance is 530 mOhms, and the self-resonant frequency is 10 MHz at 1 MHz test frequency. The package size is 1212 (3030 metric), measuring 3.00mm x 3.00mm x 1.40mm. It operates within a temperature range of -40°C to +105°C.

Fixed Inductors Feature Summary

• Shielded wire-wound design minimizes magnetic flux leakage and reduces electromagnetic interference.
• Ferrite core construction ensures stable inductance characteristics under varying load conditions.
• Compact 1212 footprint allows for high-density PCB layouts in space-constrained designs.

Fixed Inductors Applications

• Automotive electronics systems
• Power supply filtering circuits
• DC-DC converter output stages

Fixed Inductors Procurement Notes

Verify the specific suffix MMRE against official Murata documentation to confirm packaging type and material specifications. Ensure the procurement source provides valid RoHS compliance certificates. Cross-reference the manufacturer part number with authorized distributor databases to avoid counterfeit components. Confirm that the delivered quantity matches the required reel or cut tape specifications for automated assembly processes.

Fixed Inductors Selection Notes

Select this component when a shielded inductor is required to prevent magnetic coupling issues in dense layouts. The 22 µH value and 750 mA current rating suit moderate power applications. Consider the 10 MHz self-resonant frequency for high-frequency switching environments. Compare against non-shielded alternatives if magnetic field containment is not critical to the system design.
