Fox Electronics introduces the FK122 tuning fork crystal. It is approximately 33% smaller than previous models, measuring just 2.1 mm x 1.3 mm with a very low profile of 0.6 mm. The miniature size of the FK122 watch crystal makes it ideal for portable and handheld devices where space is critical.

With a frequency of 32.768 kHz, the FK122 is optimized for a standard 12.5 pF load capacitance, with an optional load capacitance of 9 pF available. Frequency tolerance is ±20 PPM at 25°C and frequency stability is -0.04 ppm/(Δ°C)² over the standard operating temperature of -40°C to +85°C.

Turnover temperature range is +20°C to +30°C and storage temperature is -55°C to +125°C. Maximum equivalent series resistance of the FK122 crystal is 90 KΩ and insulation resistance is 500 MΩ at 100 V_DC. Aging is ±3 PPM per year. The termination finish is gold over nickel.
