What are the key features of LQW18AN39NJ00D?
- 39 nH inductance with ±5% tolerance and high Q factor of 40 for efficient RF matching and tank circuit performance at VHF and lower-UHF frequencies
- 400 mA DC current rating with 0.26 Ω DC resistance in a compact 0603 (1608 metric, 1.6 mm x 0.8 mm) wire-wound chip package
- Wire-wound construction on a non-magnetic core delivers stable inductance and minimal core losses across RF operating frequencies from 100 MHz to 2 GHz
What is LQW18AN39NJ00D used for?
LQW18AN39NJ00D is used in RF impedance matching networks, LC filter stages, and VCO tank circuits in wireless communication modules operating in the 100 MHz to 1 GHz frequency range where 39 nH inductance and a Q of 40 provide low insertion loss. Its 400 mA current rating allows use as a bias choke in LNA and mixer supply decoupling networks in 2G, 3G, and sub-GHz IoT radio front-ends. The 0603 package size enables high-density PCB placement in compact RF modules for smart meters, industrial wireless sensors, and RFID reader designs.

Frequently Asked Questions
What inductance value, tolerance, and Q factor does LQW18AN39NJ00D offer for RF matching applications?
LQW18AN39NJ00D provides 39 nH nominal inductance with ±5% tolerance and a Q factor of 40 at the rated RF test frequency. These parameters make it well suited for impedance matching networks in sub-GHz wireless systems from 100 MHz to 900 MHz, where a stable 39 nH inductance value ensures consistent resonance frequency and the Q of 40 minimizes insertion loss in narrow-band LC filter topologies.
What maximum DC current and DCR does LQW18AN39NJ00D support, and how does this affect bias choke design?
LQW18AN39NJ00D is rated for 400 mA maximum DC current with a DC resistance of 0.26 Ω. At full rated current, the DC voltage drop is approximately 104 mV, which designers must account for when using this inductor as an RF bias choke in LNA or mixer supply rails operating from 3.3 V or 5 V supplies to ensure adequate headroom for the active device biasing.
How does LQW18AN39NJ00D compare to LQW18AN6N2C00D in selecting an inductor for different RF frequency bands?
LQW18AN39NJ00D offers 39 nH inductance with ±5% tolerance and 400 mA rated current, targeting sub-GHz RF applications from 100 MHz to 900 MHz, while LQW18AN6N2C00D provides 6.2 nH with a tighter ±0.2 nH tolerance and 750 mA rated current for higher-frequency 1 GHz to 6 GHz designs. Engineers choose the 39 nH variant for lower-frequency bands like 433 MHz or 868 MHz ISM applications, and the 6.2 nH variant for 2.4 GHz Wi-Fi or 5 GHz UNII band matching circuits.
