Fox Electronics Introduces the FX122, the New Miniature Tuning Fork for Portable and Handheld Devices
Fox Electronics Introduced range of watch crystals with smaller miniature tuning fork, the FX122. 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, 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 degrees C (77 degrees F) and frequency stability is -0.04 PPM / (change in Celsius degrees)(2) over the standard operating temperature of -40 degrees C to +85 degrees C (-40 degrees F to 185 degrees F).
Turnover temperature range is +20 degrees C to +30 degrees C (68 degrees F to 86 degrees F) and storage temperature is -55 degrees C to +125 degrees C (-67 degrees F to 257 degrees F). Maximum equivalent series resistance of the new FX122 crystal is 90 k ohm and insulation resistance is 500 megaohm at 100 V(DC). 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.
Price of FX122 is $0.53 in quantities of 102K. Delivery is stock to 12 weeks ARO.
