What are the key features of LQW18AN39NG00D?
- 39 nH inductance with tight ±2% tolerance ensures precise resonant frequency accuracy in VHF and UHF RF filter and matching networks
- Compact 0603 (1608) wirewound chip package enables placement in space-constrained RF front-end layouts alongside 0402 passives
- High Q factor of 40 minimizes insertion loss in RF bandpass and low-pass filter stages operating in the hundreds of MHz range
What is LQW18AN39NG00D used for?
The LQW18AN39NG00D is designed for RF impedance matching, bandpass filtering, and noise suppression in Bluetooth, Wi-Fi, and cellular front-end circuits operating in the VHF through UHF frequency range. Its 39 nH inductance at ±2% tolerance provides the precision required for LC ladder networks where resonant frequency must be tightly controlled to meet channel selectivity requirements. The 400 mA DC current rating also supports use in RF power amplifier bias chokes and antenna matching networks in low-power wireless modules.

Frequently Asked Questions
What are the inductance and current specifications of the LQW18AN39NG00D, and which RF applications do they suit?
The LQW18AN39NG00D offers 39 nH inductance at ±2% tolerance with a 400 mA rated DC current and 0.26 Ω DC resistance. These specifications suit RF bias choke and impedance-matching applications in Bluetooth and Wi-Fi front-ends where the inductor must block RF frequencies above 100 MHz while passing DC bias current to an LNA or power amplifier stage without excessive resistive voltage drop.
How does the 0603 package size of the LQW18AN39NG00D compare to the 0805 LQW2BHN39NG03L for the same 39 nH inductance?
The LQW18AN39NG00D occupies a 1.6 mm x 0.8 mm (0603) footprint, which is approximately 40% smaller in area than the 2.0 mm x 1.5 mm (0805) footprint of the LQW2BHN39NG03L. The trade-off is a lower current rating of 400 mA and higher DC resistance of 0.26 Ω versus 0.09 Ω for the 0805 device, making the 0603 variant the right choice when board space is the primary constraint and current is below 400 mA.
Why is the ±2% inductance tolerance of the LQW18AN39NG00D important for RF bandpass filter design?
In an LC bandpass filter tuned to a specific channel in the 2.4 GHz or 5 GHz ISM band, the center frequency is proportional to 1 divided by the square root of the LC product. A ±2% tolerance on the 39 nH inductor limits center frequency error to approximately ±1%, which typically keeps the passband within the channel allocation mask without requiring factory trimming, reducing production testing overhead compared to using ±5% or ±10% tolerance inductors.
