What is LQG15HS3N9C02D?
The LQG15HS3N9C02D is a fixed SMD inductor from muRata offering a precise 3.9nH inductance, 750mA rated current, and a low 140mΩ DC resistance. Designed for high-frequency circuits, this RoHS-compliant component delivers stable performance in compact, space-constrained designs.
✔ RoHS Compliant / ✔ SMD / ✔ muRata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- RF Impedance Matching: The 3.9nH ±0.2nH tight tolerance ensures precise matching in antenna circuits and front-end modules, minimizing signal reflection.
- High-Frequency Filtering: Its low DCR (140mΩ) and high self-resonant frequency (above 6GHz) make it ideal for rejecting noise in Wi-Fi and Bluetooth paths without adding loss.
- DC-DC Converter Snubbers: With a 750mA current rating, this inductor handles moderate power in snubber or bootstrap circuits, reducing switching spikes in portable electronics.
Key Features & Advantages
- Ultra-Low DCR (140mΩ): Minimizes I²R losses, boosting efficiency in battery-powered devices where every milliwatt counts.
- High Current Handling (750mA): Supports peak currents beyond the DC rating, providing design margin for transient loads.
- Controlled Inductance (3.9nH): Tight tolerance (±0.2nH) ensures repeatable RF performance across production batches.
Frequently Asked Questions
- Q: What makes LQG15HS3N9C02D different from a standard ferrite bead?
A: Unlike a lossy ferrite, this is a true inductor with a defined 3.9nH inductance and high Q, enabling resonant circuits and impedance matching where phase behavior matters. - Q: Is LQG15HS3N9C02D RoHS compliant?
A: Yes, as a muRata product, it is fully RoHS compliant and lead‑free, suitable for global manufacturing. - Q: What is the MOQ?
A: We support small batch orders for prototyping and full BOM kitting at SZYY, with flexible quantities.
