Tuning fork crystal is 33% smaller

Measuring just 2.1 x 1.3 x 0.6 mm, the FX122 tuning fork crystal is claimed to be 33% smaller than the company’s previous models. The small size msuits the device for portable and handheld devices.

With a frequency of 32.768 kHz, the part 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/ (∆C°)2 over the standard operating temperature of –40° to 85°C.

Turnover temperature range is 20° to 30°C and storage temperature is –55° to 125°C. Maximum equivalent series resistance is 90 kΩ, and insulation resistance is 500 MΩ at 100 Vdc. Aging is ±3 ppm per year. ($0.53 ea/102,000 — stock, 12 weeks ARO.)
