Compact tuning fork crystal offers stable and predictable performance
The ECX-12R crystal from ECS Inc, which produces a frequency output of 32.768 kHz, is rated for operation over a broad industrial temperature range. Low drive power makes it suitable for use in wearable devices.
The ECS Inc ECX-12R 32.768 kHz tuning fork crystal is an ideal timing device for automotive, industrial, IoT and wearable applications thanks to its stable frequency output over an operating-temperature range of -40°C to 85°C. Frequency tolerance options are ±20 ppm or ±10 ppm.
Supplied in a 2.0 mm x 1.2 mm x 0.6 mm package, the ECX-12R features a load capacitance of up to 12.5 pF. The temperature coefficient is -0.033 ppm/°C² over the operating temperature range, and first year aging at 25°C is specified at ±3 ppm. This means that designers can rely on the crystal’s accuracy throughout the standard operating lifetime of the design.
