Product Overview

LQW15AN18NG00D is a high-frequency and high-precision Chip Inductor from the LQW15AN series launched by Murata Manufacturing Co., Ltd., specifically designed for high-frequency circuit design of high-end electronic equipment. With a precise inductance value of 18nH and a high-accuracy Grade G tolerance (±2%), it features a high rated current of 370mA, a maximum DC resistance of only 0.27Ω, and a minimum Q value of 25. The self-resonant frequency reaches up to 4.5GHz, and the product operates stably within an ultra-wide temperature range of -55℃~+125℃. Its compact 0402 (1005) package size (1.0×0.6×0.5mm) and excellent high-frequency characteristics make it widely suitable for scenarios requiring strict signal transmission accuracy and reliability, such as 5G communication, consumer electronics, and automotive electronics, serving as an ideal component solution for high-frequency and high-density circuits.
