What are the key features of LQW18AN47NG00D?
- Tight ±2% inductance tolerance ensures precise RF circuit tuning and consistent performance in production runs
- Wire-wound construction in 0603 (1608) package achieves a Q factor of 38 for low-loss RF filtering and impedance matching
- 380 mA current rating and 0.29 Ω DC resistance optimize efficiency in low-power RF front-end and antenna matching circuits
What is LQW18AN47NG00D used for?
The LQW18AN47NG00D is designed for high-precision RF filtering, impedance matching, and signal conditioning in wireless communication circuits operating at frequencies up to several GHz. Its tight ±2% inductance tolerance makes it particularly valuable in frequency-sensitive applications such as Bluetooth, Wi-Fi, and LTE antenna matching networks where component variation directly impacts RF performance. The compact 0603 footprint and wire-wound construction also suit noise suppression and tank circuit applications in RF module designs requiring stable inductance across operating temperatures.

Frequently Asked Questions
How does the ±2% tolerance of LQW18AN47NG00D compare to standard ±5% RF inductors, and when does it matter?
The LQW18AN47NG00D offers a ±2% tolerance on its 47 nH inductance, compared to the more common ±5% tolerance. This tighter tolerance reduces center frequency shift in LC resonant circuits by more than half, which is critical for narrow-band RF filters in Bluetooth, GNSS, and LTE applications where a 2.5 nH deviation would unacceptably shift the resonant frequency.
Which RF circuit stages benefit from the LQW18AN47NG00D's 380 mA current rating and 0.29 Ω DC resistance?
RF power amplifier output matching networks, LNA bias chokes, and antenna feed circuits benefit most from the LQW18AN47NG00D's 380 mA current capability and low 0.29 Ω DC resistance. The low DCR minimizes ohmic losses in the signal path, helping maintain overall system efficiency in mobile and IoT device RF front-ends where power consumption must stay below a few hundred milliwatts.
For a 2.4 GHz Bluetooth antenna matching circuit, how does the LQW18AN47NG00D's 0603 package size affect PCB layout?
The LQW18AN47NG00D occupies a 1.6 mm × 0.8 mm footprint in the 0603 (1608 metric) package, enabling antenna matching networks to be placed very close to the RF IC output pad. Shorter trace lengths at 2.4 GHz reduce parasitic inductance and radiation losses, while the wire-wound Q of 38 preserves signal energy in the matching network. This combination supports compact RF front-end layouts in space-constrained modules and wearable device designs.
