7M-20.000METJ-T

Crystals Overview

The TXC Corporation 7M-20.000METJ-T is a quartz crystal resonator designed for surface-mount applications. It operates at a fundamental frequency of 20 MHz with a load capacitance of 18 pF and an equivalent series resistance (ESR) of 50 Ohms maximum. The component exhibits a frequency tolerance of ±10 ppm at 25°C and maintains a stability of ±10 ppm across the operating temperature range of -30°C to +85°C. Packaged in a compact 4-SMD, No Lead form factor, it supports commercial-grade timing requirements.
