The Epson MC-146 32.768KA-AC3 is a 32.768 kHz tuning fork crystal designed for precision timing applications. It operates in fundamental mode with a load capacitance of 9 pF and a frequency tolerance of ±20 ppm at +25°C. The equivalent series resistance (ESR) is 65 kΩ maximum, ensuring reliable oscillation in low-power circuits.
This crystal offers a wide operating temperature range of -40°C to +85°C and can be stored between -55°C and +125°C. Key electrical characteristics include a typical motional capacitance of 1.9 fF, shunt capacitance of 0.8 pF, and a maximum drive level of 1.0 μW. Frequency aging is limited to ±3 ppm per year, supporting long-term stability.
The component is housed in a compact 4-SMD flat leads package measuring 7.0 mm x 1.5 mm x 1.4 mm, suitable for surface mount assembly. It is lead-free (Pb free) as verified by the datasheet. Typical applications include real-time clocks, small communication devices, and battery-powered electronics requiring accurate timekeeping.
