Working Principle

The 402F19222IKR crystal works by forming an oscillator-amplifier arrangement. The oscillator consists of a quartz crystal that is encapsulated in an epoxy package and connected to an external circuit. The external circuitry consists mainly of an amplifier, capacitors and inductors, which are used to shape the oscillator\'s output frequency.

The crystal vibrates or “resonates” when a small electric current is passed through it, producing an oscillating voltage waveform. This waveform is amplified by the amplifier, and the resulting amplified signal is then used by the external circuit to produce the desired output frequency. The frequency of the output can be adjusted by changing the components in the external circuit.
