445A23L12M00000

Working Principle

The 445A23L12M00000 crystal is based on a piezoelectric principle. Inside the crystal is a piece of cut quartz with precisely controlled dimensions. This quartz is placed between electrodes and connected to an oscillator circuit. When an AC voltage is applied to the electrodes, the quartz crystal vibrates along its length, which in turn causes an oscillatory motion in the surrounding circuit. The frequency at which these oscillations take place is determined by the mechanical properties of the crystal.

The frequency of the vibrating crystal can be tuned to a specific frequency by changing the size of the crystal (by cutting) or by attaching different weights to the crystal (adding mass). Increasing the size of the quartz crystal causes a decrease in its resonance frequency, while adding mass increases the resonance frequency.

To ensure the highest accuracy of the 445A23L12M00000 crystal, the crystal is subjected to numerous precise tests and measurements before it is sealed and put into mass production.
