What are the key features of LQW18AN43NG00D?
- 43 nH inductance with tight 2% tolerance and Q factor of 40, enabling precise RF filter and impedance matching networks in the 0603 (1608) package
- Rated at 380 mA DC current with only 0.29 ohm DC resistance, minimizing insertion loss in RF signal paths and low-power wireless front-end circuits
- Wire-wound construction on a ferrite core in the compact 1608 (0603) case size, delivering stable high-Q performance across RF frequency bands used in Bluetooth, Wi-Fi, and IoT applications
What is LQW18AN43NG00D used for?
The LQW18AN43NG00D is designed for RF impedance matching, LC filter networks, and EMI suppression circuits in wireless communication modules operating across Bluetooth, Wi-Fi, and sub-GHz IoT frequency bands. Its 43 nH inductance and high Q factor of 40 make it well suited for narrow-band matching networks in RF front-end designs where component size must remain within the compact 0603 footprint. The 380 mA current rating also allows use in low-power DC-DC converter output filters where both RF performance and moderate current handling are required.

Frequently Asked Questions
What inductance value and tolerance does the LQW18AN43NG00D provide for RF circuit design?
The LQW18AN43NG00D provides a nominal inductance of 43 nH (0.043 µH) with a tight 2% tolerance. This precise inductance value is essential in RF impedance matching networks and bandpass filters for Bluetooth (2.4 GHz) and other ISM-band wireless front-ends where component variation directly degrades filter center frequency accuracy.
What is the maximum DC current rating and DC resistance of the LQW18AN43NG00D and how do these affect circuit performance?
The LQW18AN43NG00D is rated for 380 mA maximum DC current with a DC resistance (DCR) of 0.29 ohm. At full rated current the resistive power loss is approximately 41 mW, ensuring the compact 0603 inductor remains within its thermal limits while introducing minimal voltage drop in RF bias-T circuits or low-power 3.3 V regulator output filters.
How does the Q factor of 40 in LQW18AN43NG00D compare to ceramic core inductors for Bluetooth antenna matching?
A Q factor of 40 at the rated test frequency indicates low resistive loss relative to inductive reactance, making the LQW18AN43NG00D more efficient than many ceramic-core alternatives that achieve Q values below 30 in the same 0603 package. For Bluetooth antenna matching at 2.4 GHz, a higher Q reduces insertion loss in the matching network, improving transmit power delivery to the antenna by fractions of a dB, which can meaningfully extend wireless range.
Which package size is LQW18AN43NG00D and does it fit standard 0603 PCB land patterns?
The LQW18AN43NG00D uses the 1608 metric case size, which corresponds exactly to the 0603 imperial package measuring 1.6 mm x 0.8 mm. It is fully compatible with standard 0603 PCB land patterns and reflow soldering processes at peak temperatures up to 260 degrees C, making it a drop-in fit for existing 0603 inductor footprints in RF PCB designs.
