Typical Applications & Why This Part Fits

• Smartphone Power Rails: The 2.2 µH value and 750 mA current rating suit core supply decoupling in battery-powered handhelds, while the 375 mΩ DCR minimizes I²R losses.
• Wearable DC-DC Converters: Its small SMD footprint and low profile enable integration in compact wrist-worn electronics without sacrificing ripple suppression.
• IoT Module Noise Filtering: The fixed inductance and low DC resistance provide clean, stable filtering for RF and digital logic lines in connected devices.

Key Features & Advantages

• Low DC Resistance (375 mΩ): Reduces thermal buildup and improves overall power conversion efficiency, especially in continuous-current applications.
• 750 mA Current Handling: Supports moderate-load circuits while maintaining stable inductance–ideal for intermediate-voltage buses.
• muRata LQM Construction: Multi-layer ferrite technology ensures high reliability and excellent DC bias performance across temperature.

Frequently Asked Questions

1. Q: What makes LQM18PN2R2MFRL different from a standard wire-wound inductor?
   A: Its multilayer ceramic structure provides better high-frequency noise attenuation and a flatter inductance vs. current curve than typical wire-wound types, making it more stable under load.
2. Q: Is LQM18PN2R2MFRL RoHS compliant?
   A: Yes, as a muRata product, it is standardly RoHS compliant and lead-free, compatible with lead-free soldering processes.
3. Q: What is the MOQ?
   A: We support small batch orders and full BOM kitting at SZYY.
