ECS Electronic Component Highlight Surface Mount Crystals

The ECS-2012MV-327KE is a 2.0 mm x 1.2 mm 32.768 kHz HCMOS oscillator with MultiVoltTM capabilities. This small electronic component offers low current consumption and improved stability against uncompensated crystal oscillators.  

The ECS-3215MV-327KE series of HCMOS oscillators are in a 2.0 mm x 1.2 mm x 0.85 mm ceramic package that offers MultiVoltTM capabilities. These electronic components offer a frequency of 32.768 kHz with a frequency stability of -150 to +10 ppm and low 0.5µA current consumption at the standard industrial operating temperature of -40ºC to +85ºC. As a part of the MultiVoltTM series of oscillators, the ECS-2012MV-327KE is designed to operate on a variable supply voltage of 1.2V to 5.5V or a standard 1.8V, 2.5V, 3.0V or 3.3V supply. As it offers improved stability against various uncompensated crystal oscillators, this component is ideal smart meter, wearable, industrial and IoT applications.
