What are the key features of LQW18AN3N6C00D?
- 3.6 nH inductance with tight ±0.2 nH absolute tolerance enables precise RF impedance matching in high-frequency circuits above 1 GHz where small inductance variations shift resonant frequency significantly
- Ultra-low DCR of 0.059 Ω with 850 mA rated DC current minimizes resistive losses in high-current RF bias and choke applications, reducing thermal rise in compact PCB layouts
- Non-magnetic air-core equivalent winding with shielding suppresses magnetic field radiation, reducing EMI coupling to adjacent sensitive analog and RF circuits on the same board
What is LQW18AN3N6C00D used for?
The LQW18AN3N6C00D is designed for high-frequency impedance matching, resonant filter tanks, and RF choke applications in 5G sub-6 GHz, Wi-Fi 6, and UWB transceiver front ends. Its very low 3.6 nH inductance and tight ±0.2 nH tolerance are essential in narrow-band antenna matching networks and power amplifier output matching circuits where frequency accuracy within a few MHz is required. The 0603 package and high 850 mA current rating make it suitable for compact power-efficient RF front-end modules in smartphones and IoT devices.

Frequently Asked Questions
Why is the ±0.2 nH absolute tolerance of LQW18AN3N6C00D important in 5G or Wi-Fi 6 antenna matching?
At 3.6 nH, a ±0.2 nH tolerance represents approximately ±5.5% variation, which translates to a resonant frequency shift of about ±2% to ±3% in a typical 2.4 GHz or 5 GHz LC matching network. Tighter absolute tolerance reduces this frequency offset, ensuring impedance match stays within the target VSWR specification across the production population without requiring individual board-level tuning, which is critical for high-volume 5G and Wi-Fi 6 module manufacturing where per-unit calibration is too costly.
How does the 850 mA current rating and 0.059 Ω DCR of LQW18AN3N6C00D benefit power amplifier bias choke design?
A PA bias choke must pass DC supply current to the amplifier drain or collector while presenting high RF impedance at the operating frequency. The LQW18AN3N6C00D's 850 mA rating exceeds the typical supply current of 200 mA to 600 mA drawn by low-to-medium power RF amplifiers, and its 0.059 Ω DCR produces less than 50 mW of dissipation at maximum current, keeping the choke within safe thermal limits without additional heatsinking in space-constrained RF module layouts.
Is LQW18AN3N6C00D a suitable alternative to a 0402-package 3.6 nH inductor in a miniaturized RF design?
LQW18AN3N6C00D uses an 0603 (1.6 mm x 0.8 mm) footprint, which is larger than a 0402 (1.0 mm x 0.5 mm) package, so it is not a direct drop-in replacement on a 0402 footprint. However, the 0603 size provides access to tighter inductance tolerance and higher current ratings than comparable 0402 inductors at 3.6 nH, making the trade-off in board area worthwhile when RF matching accuracy and current handling above 500 mA are both required in the same design.
