CM155-32.768KDZFTR

The CM155-32.768KDZFTR is a 32.768 kHz tuning fork crystal (kHz crystal) manufactured by Citizen Finedevice Co., Ltd. It features a nominal frequency of 32.768 kHz with a frequency tolerance of ±20 ppm at reference temperature. The load capacitance is specified as 12.5 pF typical. Maximum equivalent series resistance (ESR) is 65 kΩ. The crystal operates in fundamental mode.\n\nThis component is designed for use as a clock source in communication equipment, AV equipment, OA equipment, cameras, cellular phones, pagers, and measuring instruments. Its low power consumption makes it suitable for portable and high-density circuit board applications.\n\nThe crystal is packaged in a 4-SMD flat lead surface mount package with three leads (CM155 series). Dimensions are 6.80 mm length, 3.00 mm width, and 1.65 mm height. It is supplied in tape and reel packaging with a standard quantity of 3000 pieces per reel.\n\nElectrical characteristics include drive level of 1 µW maximum, insulation resistance of 500 MΩ minimum at 100 VDC, and aging of ±3 ppm maximum in the first year. The component has a shock resistance of ±5 ppm maximum (drop test from 75 cm or 3000G). Sealing leakage is 1×10⁻² µPa·m³/s maximum.
