What is LQG15HN39NJ02D?
The LQG15HN39NJ02D is a fixed SMD inductor manufactured by muRata. Key specs include 39 nH inductance, 250 mA rated current, and a DC resistance of 1.06 Ω. RoHS compliant, it is designed for high-frequency circuits where precise inductance and minimal signal loss are critical.
✔ RoHS Compliant / ✔ SMD / ✔ muRata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- RF Impedance Matching: The tight 39 nH value and low 1.06 Ω DCR ensure minimal insertion loss in matching networks for 2.4 GHz ISM band modules.
- High-Frequency Filtering: Its compact SMD form and stable inductance up to several hundred MHz make it ideal for LC filter designs in portable transceivers.
- Antenna Tuning: 250 mA current handling supports power amplifier bias paths while maintaining a consistent 39 nH resonance point.
Key Features & Advantages
- Precise 39 nH Inductance: Tight tolerance (±5% typical) ensures repeatable circuit performance without manual tuning.
- Low DC Resistance (1.06 Ω): Reduces I²R power losses in continuous current paths, improving overall efficiency.
- Miniature SMD Package: Saves board space in dense RF layouts while supporting standard reflow soldering processes.
Frequently Asked Questions
- Q: What makes LQG15HN39NJ02D different from a standard ceramic chip inductor?
A: It offers a higher self-resonant frequency (SRF > 1.5 GHz) and better Q factor at UHF frequencies, thanks to muRata’s proprietary LQG15H multilayer construction. - Q: Is LQG15HN39NJ02D RoHS compliant?
A: Yes, as a muRata product, it is fully RoHS compliant and manufactured without lead or other restricted substances. - Q: What is the MOQ?
A: We support small batch orders for prototyping as well as volume requirements for production runs.
