Low Profile Crystal
Tue, 06/18/2002 - 12:41pm
The FSX327 measures 7.0 × 1.5 mm and has a low profile of 1.4 mm. It is a cost-effective alternative to custom miniature, low profile watch crystals used in space-confined real time clock applications. With a frequency of 32.768 kHz, the FSX327 is optimized for a 12.5 pF load capacitance. Frequency tolerance is 20 to +20 ppm at 25°C and frequency stability is 0.03 ± 0.01 ppm over 40°C to +85°C. Turnover temperature range is +20°C to +30°C; operating temperature is 40°C to +85°C; and storage temperature is 55°C to +125°C. Minimum insulation resistance is 500 MΩ at 100 V DC and maximum equivalent series resistance is 65 kΩ.
