CM309E6000000ABJT

The CM309E6000000ABJT is a surface mount AT-cut crystal unit manufactured by Citizen Finedevice. This crystal operates at a nominal frequency of 6.0000MHz in fundamental mode and is designed for a load capacitance of 18pF. It offers a frequency tolerance of ±30ppm and frequency stability of ±30ppm over the operating temperature range of -10°C to 60°C. The equivalent series resistance (ESR) is specified at 80Ω, with a shunt capacitance of 5.0pF maximum and a drive level of 100μW. The crystal exhibits aging of ±5ppm in the first year and provides insulation resistance of 500MΩ minimum.

The crystal is housed in a compact 4-SOJ (Small Outline J-lead) package with a 9.60mm pitch, measuring 11.70mm x 4.80mm x 3.70mm. It is designed for surface mount mounting and is supplied in tape and reel packaging with 1,000 pieces per reel. The component is RoHS compliant and has an MSL rating of Level 1 (unlimited).

Typical applications include consumer electronics where a stable frequency reference is required, such as microcontrollers, timing circuits, and communication interfaces. The AT-cut design provides good frequency stability over temperature, making it suitable for general-purpose timing applications.
