Epson offers a vast range of 32.768kHz watch crystal products. Their focus and recommended models for new designs are sub miniature series that offer a wide range of options. Larger packages are available, please enquire.
FC1610AN (1.6×1.0mm) . Smallest in the range, ideal for compact communication devices. Available at +/-20ppm with either 9pF or 12.5pF load capacitance.
FC-12M (2.05×1.2) . Predominately a 32.768kHz device but available in other kHz frequencies too. +/-20ppm or +/-30ppm options with 12.5pF load capacitance. A low ESR version (FC2012AN) in this size is also available.
FC-135 (3.2×1.5) . Now an industry standard. +/-10ppm and +/-20ppm (std) available in a variety of load capacitances either 7pF, 9pF or 12.5pF. An automotive qualified AEC-Q200 version (FC-13A) and low ESR option (FC-135R) are options in this 3.2×1.5mm series too, giving great flexibility.
