具備優良耐壓性能和低損耗的SMD晶振編碼Q22FA2380175400，伴隨著市場的需求不斷變化，需要不斷地發現需求，解決新的需求，當我們有意識關注到晶振行業的發展時，說明它對于我們生活上的影響并不大，但是也是不容忽視的存在，作為元器件中第二重要的心臟，能夠決定產品的性能優秀程度，我們能夠在發現石英晶振的獨特，同時也能發現石英晶振是采用石英晶片制成的計算機的計時器通常是一個精密加工過的石英晶體，石英晶體在其張力限度內以一定的頻率振蕩，這種頻率取決于晶體本身如何切割及其受到張力的大小。有兩個寄存器與每個石英晶體相關聯，一個計數器和一個保持寄存器。

石英晶體的每次振蕩使計數器減1。當計數器減為0時，產生一個中斷，計數器從保持寄存器中重新裝入初始值。這種方法使得對一個計時器進行編程，令其每秒產生60次中斷（或者以任何其它希望的頻率產生中斷）成為可能，每次中斷稱為一個時鐘嘀嗒。
SMD晶振在電氣上可以等效成一個電容和一個電阻并聯再串聯一個電容的二端網絡，電工學上這個網絡有兩個諧振點，以頻率的高低分其中較低的頻率為串聯諧振，較高的頻率為并聯諧振。

具備優良耐壓性能和低損耗的SMD晶振編碼Q22FA2380175400，由于晶體自身的特性致使這兩個頻率的距離相當的接近，在這個極窄的頻率范圍內，晶振等效為一個電感，所以只要晶振的兩端并聯上合適的電容它就會組成并聯諧振電路。
