At 3.2 x 1.5 mm and a 0.9 mm profile, this is the smallest miniature watch crystal available. It is made for tight quarters, such as in portable or handheld devices. It has a frequency of 32,768 kHz, and the surface mount device offers a standard 12.5 pF load capacitance in the FX135A model, and an optional 9 pF capacitance in the FX135B. With a standard operating temperature of -40 to 85C (-40 to 185F), it has a frequency stability of -0.045 ppm/( C )2 and a frequency tolerance of +/-20 PPM at 25C (77 F). Turnover temperature range is 20 to 30C (68 F to 86 F) and storage temperature is -55 to 125C (-67 to 257F). It has a maximum equivalent series resistance of 50 k and insulation resistance of 500 M at 100 VDC. It has a gold-over-nickel finish, and aging is ±3 PPM per year. It is RoHS-compliant. The crystal comes standard in a 3,000-unit taps and reel.
