Additional Details

The inductance value is 1.8 nH. It comes in a 0402 package size. Key specifications include the inductance tolerance (typically ±5%), the Q factor (which can be greater than 20 at specific test frequencies), and the self-resonant frequency (which is usually well above 1 GHz). This inductor is commonly used in impedance matching networks, where it helps to match the impedance of different circuit elements, maximizing signal transfer and minimizing reflections. It's also valuable in RF filter designs, where it helps to selectively block or pass specific frequency ranges. Its high self-resonant frequency ensures that the inductor behaves as an inductor, rather than a capacitor, at the operating frequencies of the circuit. Its small size and robust design make it an excellent choice for a wide variety of high-frequency applications, where performance and reliability are critical.
