The Epson MC-146 32.7680KA-A is a tuning fork crystal designed for low-frequency timing applications. It operates at a nominal frequency of 32.768 kHz with a frequency tolerance of ±20ppm at +25°C. The crystal requires a load capacitance of 12.5pF and features a maximum equivalent series resistance (ESR) of 65 kΩ.
This crystal is housed in a compact surface-mount package (4-SMD, Flat Leads) measuring 6.70mm x 1.50mm x 1.40mm. It operates over a temperature range of -40°C to +85°C and can be stored between -55°C and +125°C. The drive level is limited to 1.0 μW maximum, with typical motional capacitance of 1.9 fF and shunt capacitance of 0.8 pF.
Typical applications include real-time clock (RTC) circuits, small communications devices, and other low-power timing systems requiring precise frequency generation. The crystal is RoHS3 compliant per the manufacturer's datasheet.
