描述

The E8WSDC07-32.768K is a watch crystal resonator designed for precision timekeeping in portable and embedded systems. It operates at a nominal frequency of 32.768 kHz with a frequency tolerance of ±20 ppm at 25°C and features a maximum equivalent series resistance (ESR) of 70 kOhms and shunt capacitance of 1.6 pF. The device operates in flexural tuning fork mode with a drive level of 0.1 µW typical and 0.5 µW maximum, maintaining frequency stability of -0.040 ppm/(°C)² over temperature and aging of ±2 ppm per first year. With an operating temperature range of -40°C to +85°C and a storage range of -55°C to +125°C, this component is ideal for real-time clock (RTC) circuits, wristwatches, and other low-power timing applications requiring high accuracy and reliability.
