7B-32.000MAAJ-T

Crystals Overview

The 7B-32.000MAAJ-T is a surface-mount MHz crystal manufactured by TXC Corporation, designed for high-frequency stability in compact electronic assemblies. It operates at a nominal frequency of 32 MHz with a frequency tolerance and stability of ±30 ppm at 25°C and across the operating temperature range. The component utilizes a fundamental oscillation mode and features a load capacitance of 18 pF with an equivalent series resistance (ESR) of 40 Ohms. It is housed in a 4-SMD, no-lead package measuring 5.00 mm in length, 3.20 mm in width, and 1.05 mm in maximum height. The device supports a working temperature range of -20°C to +70°C and complies with RoHS3 standards.
