Typical Applications & Why This Part Fits

• RF Matching Networks: The 18nH value and low 360mΩ DCR make it ideal for impedance matching in GSM, Wi-Fi, and Bluetooth front-ends, minimizing signal degradation.
• DC/DC Converter Filtering: With a 400mA current rating, this inductor comfortably handles low-power supply rails in IoT modules and portable devices without saturation.
• High-Frequency Oscillator Circuits: The tightly controlled 18nH tolerance ensures consistent frequency stability in VCOs and PLL loops used in wireless transceivers.

Key Features & Advantages

• Tight Inductance Tolerance: muRata’s ceramic multilayer construction delivers ±5% tolerance on 18nH, reducing tuning overhead in mass production.
• Low DC Resistance: A 360mΩ DCR minimizes I²R losses, improving efficiency in battery-operated designs by keeping heat generation low.
• Compact SMD Package: The miniature footprint supports dense PCB layouts, freeing board space for additional functions without compromising electrical performance.

Frequently Asked Questions

1. Q: What makes LQG15HS18NJ02D different from a standard wirewound inductor?
   A: Unlike wirewound types, this multilayer chip inductor offers a self-resonant frequency above 2 GHz, making it uniquely suited for RF circuits where parasitic capacitance must be minimised.
2. Q: Is LQG15HS18NJ02D RoHS compliant?
   A: Yes, as a muRata product, it is standardly RoHS compliant and lead-free, fully meeting current EU directives.
3. Q: What is the MOQ?
   A: We support small batch orders to accommodate prototypes and low-volume production runs.
