ACT200A 32.768KH – ACT CRYSTAL

The ACT200A 32.768KH is a quartz crystal resonator manufactured by ACT, designed for real-time clock (RTC) and microcontroller applications requiring a precise 32.768 kHz frequency reference. Encapsulated in a hermetically sealed 8.0mm x 3.8mm surface-mount package, this crystal exhibits a specified frequency tolerance at 25°C, typically ±20 ppm, and a load capacitance (CL) optimized for stable oscillation within standard RTC oscillator circuits. The equivalent series resistance (ESR) is critically controlled to minimize power consumption and ensure reliable start-up, typically specified at a maximum of 50 kΩ. Aging characteristics are tightly controlled to maintain long-term frequency stability, typically less than ±3 ppm per year. The crystal is manufactured using a high-purity synthetic quartz blank, cut and lapped to achieve the desired frequency and temperature characteristics.
