Abracon ABS05-32.768KHZ-T Ultra-Miniature RTC Crystal (32.768kHz, 12.5pF, 1.6x1.0mm SMD)

Keep precise, low-power system time in your ultra-compact electronics with the ABS05-32.768KHZ-T real-time clock (RTC) quartz crystal from Abracon. Operating at the industry-standard $32.768\text{ kHz}$ frequency ($2^{15}\text{ Hz}$), this crystal provides the exact clock source required by microcontrollers, RTC ICs, and low-power sleep timers to calculate precise seconds, minutes, and hours while consuming micro-amps of power.

Housed in a micro-miniature 1.6 x 1.0 x 0.5 mm surface-mount package, the ABS05 series is engineered specifically for space-constrained wearable technology, wireless IoT sensor nodes, smartwatches, and medical portables. With a standard 12.5pF load capacitance and excellent frequency stability, it ensures dependable timekeeping and fast startup performance for modern ultra-low-power microcontrollers (such as STM32, ESP32-S3, and nRF52 series).

Key Features:

• 32.768 kHz Standard Frequency: Perfectly matched for RTC peripherals, sleep-wake timers, and low-power clock generation in modern SoCs.

• Ultra-Miniature Package (1610 Metric): Tiny 1.6 x 1.0 mm footprint saves maximum PCB area in high-density wearables and IoT hardware.

• 12.5pF Load Capacitance: Fully compatible with standard microcontroller internal loading caps and external RTC oscillator circuits.

• High Frequency Stability: Tuning-fork crystal design ensures accurate timekeeping across broad operating temperature ranges.
