The ABS05-32.768KHZ is a 32.768 kHz surface-mount tuning fork crystal designed for low-power timing and real-time clock applications. It features a compact form factor of 1.6 × 1.0 × 0.5 mm with a low profile suitable for height-constrained designs, operating in flexural mode with a frequency tolerance of ±20 ppm at +25°C. The device operates reliably across an extended temperature range of -40°C to +85°C, with a maximum equivalent series resistance (ESR) of 90 kO, a shunt capacitance of 1.3 pF, and a standard load capacitance of 12.5 pF. It is RoHS/RoHS II compliant and ideal for wireless modules, IoT devices, Bluetooth/BLE applications, low-power microcontrollers, and communication equipment requiring precise timing with minimal power consumption.
