E1WCDB12-32.768K
Crystal Resonator 0.032768MHz A±20ppm (Tol) 12.5pF FUND 35000Ohm 2-Pin Thru-Hole Bulk ...
DESCRIPTION
The E1WCDB12-32.768K is a watch crystal resonator designed for precision timekeeping applications, featuring a nominal frequency of 32.768 kHz with a frequency tolerance of ±20 ppm at 25°C. This tuning fork cut crystal operates in fundamental mode with a load capacitance of 12.5 pF parallel resonant configuration, delivering excellent frequency stability with a temperature coefficient of -0.034 ppm ±0.006 ppm/(°C)² and aging of ±3 ppm/year maximum. The device is housed in a compact 2.1 mm × 6.2 mm thru-hole metal cylindrical package and operates reliably across a temperature range of -20°C to +70°C, with storage capability from -40°C to +85°C. Its low equivalent series resistance of 35,000 Ohms maximum and minimal drive level requirement of 1 µW maximum make it ideal for battery-powered real-time clock circuits, wearable devices, and other low-power timing applications requiring high accuracy and stability.
