具备优良耐压性能和低损耗的SMD晶振编码Q22FA2380175400，伴随着市场的需求不断变化，需要不断地发现需求，解决新的需求，当我们有意识关注到晶振行业的发展时，说明它对于我们生活上的影响并不大，但是也是不容忽视的存在，作为元器件中第二重要的心脏，能够决定产品的性能优秀程度，我们能够在发现石英晶振的独特，同时也能发现石英晶振是采用石英晶片制成的计算机的计时器通常是一个精密加工过的石英晶体，石英晶体在其张力限度内以一定的频率振荡，这种频率取决于晶体本身如何切割及其受到张力的大小。有两个寄存器与每个石英晶体相关联，一个计数器和一个保持寄存器。

石英晶体的每次振荡使计数器减1。当计数器减为0时，产生一个中断，计数器从保持寄存器中重新装入初始值。这种方法使得对一个计时器进行编程，令其每秒产生60次中断（或者以任何其它希望的频率产生中断）成为可能，每次中断称为一个时钟嘀嗒。
SMD晶振在电气上可以等效成一个电容和一个电阻并联再串联一个电容的二端网络，电工学上这个网络有两个谐振点，以频率的高低分其中较低的频率为串联谐振，较高的频率为并联谐振。

具备优良耐压性能和低损耗的SMD晶振编码Q22FA2380175400，由于晶体自身的特性致使这两个频率的距离相当的接近，在这个极窄的频率范围内，晶振等效为一个电感，所以只要晶振的两端并联上合适的电容它就会组成并联谐振电路。
