Typical Applications & Why This Part Fits

• RF Matching Networks: The precise 3.9 nH value and low 130 mΩ DCR ensure minimal insertion loss in antenna impedance matching for IoT modules.
• High-Frequency DC/DC Converters: With 700 mA current capability and small SMD footprint, it suits point-of-load regulation in compact wireless transceivers.
• Filtering and Choke Circuits: Its consistent inductance up to several hundred MHz makes it ideal for noise suppression in Bluetooth or Zigbee front-ends.

Key Features & Advantages

• Ultra‑Tight Inductance Tolerance: The 3.9 nH ±0.3 nH ensures repeatable filter cutoff frequencies without need for additional trim.
• Low DC Resistance: At only 130 mΩ, it minimizes I²R losses even at the full 700 mA load, improving overall system efficiency.
• Monolithic Construction: muRata’s multilayer ceramic process yields high self‑resonant frequency and excellent temperature stability for demanding environments.

Frequently Asked Questions

1. Q: What makes LQG15HN3N9S02D different from a standard wire‑wound inductor?
   A: Its monolithic ceramic structure provides a higher SRF and lower parasitic capacitance, essential for RF circuits above 1 GHz, while maintaining a 3.9 nH stable inductance.
2. Q: Is LQG15HN3N9S02D RoHS compliant?
   A: Yes, as a muRata product, it is standardly RoHS compliant and lead‑free.
3. Q: What is the MOQ?
   A: We support small batch orders and full BOM kitting at SZYY.
