Working Principle

ECS-300-18-30BQ-DS works by changing the mechanical vibrations of high frequency oscillations through its electrodes (piezoelectric effect). Depending on the frequency that the device is tuned to, the desired emissions are produced. Essentially, the operation of a ceramic resonator involves piezoelectric and capacitive effects, both of which work by converting mechanical energy into electrical energy and vice versa.Through the use of a piezoelectric material, vibrations with a given frequency will yield acoustic energy. In contrast, a capacitor is used to couple the energy into and out of a resonator\'s electrodes, thus accomplishing the desired frequency oscillations. The combination of these two effects produces a singulated oscillation cycle with a period of time where electrical signals can pass through the resonator\'s electrodes to the load circuit.

Conclusion

ECS-300-18-30BQ-DS is a type of crystal within the high frequency ceramic resonator family. It is mainly used in wireless audio and communication applications, due to its frequency accuracy and miniature size. The way that ECS-300-18-30BQ-DS crystal type works, is by changing the mechanical vibrations of high frequency oscillations through its electrodes. This crystal is often found in consumer electronics to reduce system costs, enabling users to enjoy features like keyless entry and audio broadcasting.
