The FX135 is the smallest miniature watch crystal available, measuring just 3.2 mm x 1.5 mm with a very low profile of 0.9 mm. The extremely small size of the new FX135 watch crystal makes it ideal for applications where space is critical, such as in portable and handheld devices.
With a frequency of 32.768 kHz, these new surface mount device (SMD) are optimized for a standard 12.5 pF load capacitance. Frequency tolerance is ±20 PPM at 25°C (77°F) and frequency stability is -0.045 ppm / (ΔC°)2 over the standard operating temperature of -40°C to +85°C (-40°F to 185°F).
