What is LQG15HS4N3B02D?
The LQG15HS4N3B02D is a fixed SMD inductor manufactured by muRata (村田). Key specs include 4.3 nH inductance, 750 mA rated current, and 140 mΩ DC resistance. RoHS compliant, it is designed for high-frequency signal integrity with minimal power loss.
✔ RoHS Compliant / ✔ SMD / ✔ muRata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- RF Impedance Matching: With 4.3 nH and low 140 mΩ DCR, this inductor excels in matching networks for Bluetooth and Wi-Fi front-end modules, preserving signal strength.
- High-Frequency Filtering: The 750 mA current handling combined with a compact multilayer structure makes it ideal for DC bias circuits in VCOs and PLLs, ensuring stable oscillation.
- Wireless Charging Coils: Its low resistance minimizes thermal rise during continuous 750 mA operation, suitable for small-signal resonant circuits in NFC or wireless power receivers.
Key Features & Advantages
- Low DC Resistance (140 mΩ): Reduces I²R losses, improving overall efficiency in battery-powered portable devices.
- High Current Capacity (750 mA): Supports demanding RF power amplifiers and DC-DC converter bias lines without saturation.
- Stable Inductance vs. Frequency: muRata’s ceramic multilayer construction ensures ±0.3 nH tolerance and high self-resonant frequency for consistent GHz-band performance.
Frequently Asked Questions
- Q: What makes LQG15HS4N3B02D different from a standard wire-wound inductor?
A: This multilayer ceramic chip inductor offers a much higher self-resonant frequency (SRF) and lower parasitic capacitance than wire-wound types, making it ideal for applications above 1 GHz where wire-wound inductors would self-resonate. - Q: Is LQG15HS4N3B02D RoHS compliant?
A: Yes, as a muRata product, it is standardly RoHS compliant and lead-free. - Q: What is the MOQ?
A: We support small batch orders. Please contact our sales team for specific quantity inquiries.
