The ABS09-32.768KHZ-T is a low-profile, surface-mount (SMD) crystal designed to provide a stable 32.768 kHz timing reference. It operates with a standard load capacitance of 12.5 pF and has a maximum frequency tolerance of ±20 ppm over an industrial operating temperature range of -40°C to +85°C. Housed in a compact 4.1 x 1.5 x 0.9 mm ceramic package, it offers excellent environmental and heat resistance with a maximum equivalent series resistance (ESR) of 70 kOhms. Its small size and robust performance make it ideal for high-density circuit boards in applications such as wireless communications, commercial and industrial equipment, and various measuring instruments.
