Quartz Crystal Resonator Oscillator 14.31818MHz HC-49S

They operate on the principle of inverse piezoelectric effect which causes it to vibrate at its natural frequency and It is then converted into oscillations.it is a component used to determine frequency.

Keep your microcontroller tickin’ with a fancy timing crystal. This 14.31818 MHz model comes in an HC49S (short style) standard package and easy to use with any microcontroller or device that requires an external crystal.
