As indicated by its name, the 6K6 watch crystal is a quartz crystal sized by 2×6 in mm, and its vibrating frequency varies from 30KHz to 350KHz, making it a KHz-band crystal.
This crystal unit consumes little power as the maximum drive level is only 1μW, and its typical load capacitance ranges from 6.0pF to 12.5pF. Furthermore, the operating temperature range is either -20℃~+70℃ or -40℃~+85℃, and the aging rate is just ±3ppm/year, thus making it possible to work for a long time. Additionally, our piezoelectric quartz crystal unit also possesses good frequency stability as well as high precision and reliability.
