9B-12.000MAAJ-B

Crystals Overview

The TXC Corporation 9B-12.000MAAJ-B is a quartz crystal resonator operating at a fundamental frequency of 12 MHz. It features a frequency tolerance and stability of ±30 ppm across an operating temperature range of -20°C to +70°C. The component utilizes an 18 pF load capacitance and exhibits an equivalent series resistance (ESR) of 40 Ohms with a maximum drive level of 100 µW. Housed in the HC-49/US through-hole package, it measures 11.5 mm in length, 5.0 mm in width, and 3.68 mm in height.
