Product Announcement from Fox Electronics, Inc.
The FX122 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 new FX122 watch crystal makes it ideal for portable and handheld devices where space is critical.
With a frequency of 32.768 kHz, the new surface mount device (SMD) 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 (77°F) and frequency stability is -0.04 ppm / (ΔC°)2 over the standard operating temperature of -40°C to +85°C (-40°F to 185°F).
Turnover temperature range is +20°C to +30°C (68°F to 86°F) and storage temperature is -55°C to +125°C (-67°F to 257°F). Maximum equivalent series resistance of the new FX122 crystal is 90 kΩ and insulation resistance is 500 MΩ at 100 VDC. Aging is ±3 PPM per year. The termination finish is gold over nickel.
The new watch crystal is RoHS-compliant and comes standard in a 3,000-unit tape and reel for automatic assembly systems.
