Additional Details:

The LQN2A series utilizes a wire-wound construction which provides a high Q-factor and precise inductance. The compact size makes it ideal for densely populated circuit boards. The inductor exhibits stable performance over a wide temperature range. Key specifications include inductance value (e.g., 18nH in this case), Q-factor, self-resonant frequency (SRF), DC resistance (DCR), and rated current. This inductor is commonly used in RF front-end circuits, impedance matching networks for antennas, and high-frequency filters in wireless communication devices such as mobile phones, WLAN modules, and Bluetooth devices. The high Q-factor minimizes insertion loss in filtering applications and improves the efficiency of impedance matching circuits.
