7M-20.736MEEQ-T

Crystals Overview

The TXC Corporation 7M-20.736MEEQ-T is a surface-mount quartz crystal resonator operating at a fundamental frequency of 20.736 MHz. It features a frequency tolerance and stability of ±10 ppm across the commercial temperature range of -20°C to +70°C. The component utilizes a 10 pF load capacitance and exhibits an equivalent series resistance (ESR) of 50 Ohms with a maximum drive level of 100 µW. Physically, it is housed in a compact 4-SMD, no-lead package measuring 3.2 mm in length, 2.5 mm in width, and 0.7 mm in height.
