SMD Inductor LQG15HN18NJ02D

What is LQG15HN18NJ02D?

The LQG15HN18NJ02D is a fixed SMD inductor from muRata (Murata) designed for compact RF and high-frequency circuits. It delivers an exact inductance of 18 nH with a DC resistance of 510 mΩ and supports a continuous current up to 350 mA. The multilayer construction ensures high self-resonant frequency and minimal parasitic capacitance, making it ideal for impedance matching and filtering in space-constrained designs. RoHS compliant, this component guarantees reliable performance without environmental restrictions.

Typical Applications & Why This Part Fits

• RF Front-End Matching: Its 18 nH value and low 510 mΩ DCR minimize insertion loss in antenna matching networks for Bluetooth, Zigbee, and Wi-Fi modules.
• High-Speed Data Lines: The inductor’s tight tolerance (±2% or better) and stable Q-factor preserve signal integrity in USB 2.0, HDMI, or LVDS filtering stages.
• DC-DC Converter Output Filtering: With a 350 mA current rating and small footprint, it effectively suppresses high-frequency ripple in smartphones and IoT sensor power rails.

Key Features & Advantages

• Multi-Layer Monolithic Structure: Provides excellent solderability and mechanical strength, reducing failure risk during automated assembly.
• 510 mΩ Max DCR: Keeps I²R losses low at full rated current, improving overall system efficiency in battery-powered devices.
• 350 mA Rated Current: Adequate headroom for nominal 200-300 mA loads, ensuring stable inductance over temperature and bias.

Frequently Asked Questions

1. Q: What makes LQG15HN18NJ02D different from a standard wire-wound inductor?
   A: Unlike wire-wound types, the multilayer ceramic construction delivers a much higher self-resonant frequency (above 3 GHz) and a flat inductance response up to UHF bands, making it superior for RF filtering.
2. Q: Is LQG15HN18NJ02D RoHS compliant?
   A: Yes, as a muRata product, it is standardly RoHS compliant and lead‑free, meeting global environmental directives.
3. Q: What is the MOQ?
   A: We support small batch orders and full BOM kitting at SZYY.
