What are the key features of LQW18AN3N9C00D?
- Ultra-tight ±0.2 nH tolerance on 3.9 nH inductance enabling precise GHz-range impedance matching and LC filter resonance control
- High 850 mA rated current with extremely low 0.059 Ω DC resistance minimizing power loss in RF power amplifier bias and matching networks
- Wirewound 0603 (1608 metric) chip construction achieving Q factor of 35 for low insertion loss in sub-6 GHz wireless RF front-end designs
What is LQW18AN3N9C00D used for?
The LQW18AN3N9C00D is designed for RF impedance matching, antenna tuning, and LC bandpass filter networks in wireless devices operating from 500 MHz to above 5 GHz, including 5G NR, Wi-Fi 6, and Bluetooth modules. Its 3.9 nH inductance and ±0.2 nH tolerance deliver consistent resonant frequency across production batches, critical for yield in mass-produced RF front-end modules. The 850 mA current rating and 0.059 Ω DCR make it suitable for both signal path and bias choke applications in RF power amplifier output stages.

Frequently Asked Questions
What inductance value and tolerance does the LQW18AN3N9C00D offer and why does the tolerance matter in GHz RF designs?
The LQW18AN3N9C00D provides 3.9 nH inductance with a ±0.2 nH tolerance, which represents approximately 5% accuracy on this small value. At 2.4 GHz, a 0.2 nH deviation shifts the self-resonant frequency of an LC matching network by roughly 15 MHz, directly impacting antenna return loss and power transfer efficiency. This tight tolerance is essential for consistent yield in high-volume production of Bluetooth, Wi-Fi 6, and 5G FR1 front-end modules where batch-to-batch RF performance must be maintained within 0.5 dB.
How does the 850 mA current rating and 0.059 Ω DC resistance of the LQW18AN3N9C00D benefit RF power amplifier bias networks?
With an 850 mA rated DC current and 0.059 Ω DCR, the LQW18AN3N9C00D generates less than 50 mW of conduction loss at full current, preserving amplifier supply voltage and overall power-added efficiency in PA bias choke applications. Its high current capacity supports multi-stage RF power amplifiers in 5G handsets and IoT gateways operating at output power levels from 23 dBm to 30 dBm, where bias inductor current can reach 500 mA to 800 mA continuously.
How does the LQW18AN3N9C00D compare to the LQW18AN9N5D00D when choosing an inductor for a 2.4 GHz impedance matching network?
The LQW18AN3N9C00D provides 3.9 nH versus the LQW18AN9N5D00D's 9.5 nH, making the 3N9 variant better suited for higher-impedance transformation ratios and shorter electrical delay in 2.4 GHz matching networks requiring shunt elements below 5 nH. Additionally, the LQW18AN3N9C00D has a lower DCR of 0.059 Ω compared to 0.11 Ω and a higher 850 mA versus 650 mA current rating, giving it an edge in PA output matching stages that demand both low loss and higher DC bias current handling in a compact 0603 footprint.
