7M-20.000MAHJ-T

Crystals Overview

The 7M-20.000MAHJ-T is a surface-mount quartz crystal manufactured by TXC Corporation, designed for precision timing applications. It operates at a fundamental frequency of 20 MHz with a frequency tolerance and stability of ±30 ppm. The component features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 60 Ohms. It utilizes a 4-SMD, no-lead package measuring 3.2 mm in length, 2.5 mm in width, and 0.7 mm in height. The device supports a wide operating temperature range from -40°C to +85°C and is supplied in reel packaging.
