The Abracon ABS07-32.768KHZ-T is a 32.768 k Hz surface-mount quartz crystal in a 2-pin CSMD package measuring 3.2 mm x 1.5 mm x 0.9 mm. It is specified with a 12.5 pF load capacitance, 70 k Ohm equivalent series resistance, 0.002 percent frequency tolerance and 144 ppm frequency stability, over a -40 C to 85 C operating temperature range. A 32.768 k Hz crystal is the standard timekeeping reference because the frequency is a power of two, so a 15-stage binary divider yields exactly one pulse per second. The ABS07-32.768KHZ-T is RoHS and China RoHS compliant and supplied on tape and reel in 3, 000-piece quantities.

A 32.768 k Hz crystal in this package is used as the timekeeping reference for real-time clock circuits, low-power sleep and wake timers in microcontrollers, watchdog and calendar functions, and the RTC oscillator input on metering, wearable, and battery-powered IoT devices. The 12.5 pF load capacitance must be matched by the host oscillator circuit for the part to hold its rated tolerance. The compact 3.2 mm x 1.5 mm footprint and -40 C to 85 C range suit space-constrained consumer and industrial boards. Typical buyers are embedded and low-power hardware designers, smart-metering and IoT OEMs, and contract manufacturers sourcing timing components.
