EFO-SS Series, Resonators

Resonator products belong to the family of frequency selective elements used for generating a frequency source when combined with an external drive circuit. While they serve a similar purpose to quartz crystal devices, resonators incorporate different technologies such as surface acoustic wave (SAW) or piezoceramic materials. Resonators and quartz crystals share overlapping application spaces, but they have distinct characteristics. Resonator devices typically offer greater durability compared to quartz crystals but sacrifice some accuracy and output stability in exchange. Resonators utilize the principles of resonance to generate the desired frequency. They can be constructed using various materials, including piezoelectric ceramics or SAW devices. These materials possess unique properties that allow them to resonate at specific frequencies when subjected to an external drive signal. Resonator devices are known for their robustness and ability to withstand harsh environmental conditions, making them suitable for applications that require reliable operation in challenging settings. However, due to their design and material properties, resonators may exhibit slightly lower accuracy and stability compared to quartz crystals. The trade-off between durability and accuracy/output stability makes resonators a preferred choice in certain applications. They are commonly found in automotive electronics, industrial control systems, and other environments where reliability and resistance to vibration, shock, and extreme temperatures are critical. In summary, resonator products serve as frequency selective elements that generate a frequency source when combined with an external drive circuit. While offering enhanced durability, they may exhibit slightly reduced accuracy and stability compared to quartz crystals. Their robustness makes them well-suited for demanding applications where reliability is paramount.
