Low Profile Mini Watch Crystal for Real Time Clock Applications


STAFF -- ECN, 6/1/2002



Fox Electronics has released a miniature watch crystal that measures
7.0 mm × 1.5 mm with a low profile of 1.4 mm. The FSX327 crystal is an
alternative to custom miniature, low profile watch crystals used in
space-confined RTC applications. With a frequency of 32.768 kHz, this
crystal is optimized for a 12.5 pF load capacitance. Frequency
tolerance is 20 ppm to +20 ppm at 25°C (77°F), and frequency stability
is 0.0340°C to +85°C (40°F to 185°F). Turnover temperature range is
+20°C to +30°C (68°F to 86°F); operating temperature is 40°C to +85°C
(40°F to +185°F; and storage temperature is 55°C to +125°C (F to
+257°F). Minimum insulation resistance is 500 M? at 100 V DC, and
maximum ESR is 65 k?. Pricing begins at $0.52 in quantities of 3,000.
