CFS-20632768DZFB Description

Short technical summary and product information.

The Citizen Finedevice CFS-20632768DZFB is a precision tuning fork crystal unit designed for accurate timekeeping and frequency reference applications. It operates at a nominal frequency of 32.768 kHz with a frequency tolerance of ±20 ppm at 25°C. The crystal requires a 12.5 pF load capacitance and has a maximum equivalent series resistance (ESR) of 35 kΩ.

 

This crystal is housed in a compact cylindrical can with radial leads, measuring 1.90 mm in diameter and 6.20 mm in height, making it suitable for through-hole mounting. It operates over a temperature range of -20°C to 70°C and can be stored between -40°C and 85°C. The part is RoHS compliant and lead-free.

 

Typical applications include real-time clocks, watches, consumer electronics, and security devices where stable and accurate frequency generation is required. The fundamental operating mode ensures reliable performance in low-power circuits.
