Save energy with the 32.768 kHz KXO-V32T Oscillator

GEYER KXO-V32T with 32.768 kHz oscillator to boost your circuit

The KXO-V32T Oscillator has an extremely low current consumption of only 1.0 µA. 
This low power consumption is given at voltages up to 3.3V. In applications using other clock generators, this low value can only be achieved at lower voltages.

Your battery can last 50% longer.

As a result, our KXO-V32T is ideally suitable for applications with a long power-save mode: in sleep mode, only the clock runs in the background as an energy consumer.

Due to the accurate frequency stability, a tolerance of only ±10 ppm, there is no need for complex temperature compensations over the entire industrial temperature range.

The KXO-V32T is also suitable for battery-based sensor radio systems, for goods tracking in logistics and storage areas or for long-lasting applications, and is particularly suitable for use in medical technology.
