A resonator is an electronic component that produces a resonant frequency.

        Resonators are commonly divided into quartz crystal resonators and ceramic resonators.

        The resonator has the function of generating frequency, has the characteristics of stability, good anti-interference performance, and is widely used in various electronic products. Quartz crystal resonators have higher frequency accuracy than ceramic resonators, but they also cost more than ceramic resonators. The resonator mainly plays the role of frequency control. All electronic products need a resonator for the transmission and reception of frequencies. The types of resonators can be divided into two types: in-line and patch.
