Product Overview

LQW18AN68NG00D is a high-frequency and high-precision Chip Inductor from the LQW18AN series launched by Murata Manufacturing Co., Ltd., specifically designed for circuit design of medium and high-frequency precision electronic equipment. With a precise inductance value of 68nH and a high-accuracy Grade G tolerance (±2%), it features a minimum Q value of 22, a maximum DC resistance of 1.2Ω, and a rated current of 180mA. The self-resonant frequency reaches up to 1.8GHz, and the product operates stably within an ultra-wide temperature range of -55℃~+125℃. Its standard 0603 (1608) package size (1.6×0.8×0.8mm) and excellent high-frequency low-loss characteristics make it widely suitable for scenarios requiring strict signal accuracy and stability, such as 5G communication, consumer electronics, automotive electronics, and industrial control, serving as a core component solution for medium and high-frequency circuits.

Key Features

• High Precision & High-Frequency Adaptability: 68nH inductance with ±2% (Grade G) tolerance, stable performance at 100MHz test frequency, and a high self-resonant frequency of 1.8GHz, meeting the precise transmission requirements of medium and high-frequency signals.
