具備優(yōu)良耐壓性能和低損耗的SMD晶振編碼Q22FA2380175400，伴隨著市場(chǎng)的需求不斷變化，需要不斷地發(fā)現(xiàn)需求，解決新的需求，當(dāng)我們有意識(shí)關(guān)注到晶振行業(yè)的發(fā)展時(shí)，說明它對(duì)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(chǎn)品的性能優(yōu)秀程度，我們能夠在發(fā)現(xiàn)石英晶振的獨(dú)特，同時(shí)也能發(fā)現(xiàn)石英晶振是采用石英晶片制成的計(jì)算機(jī)的計(jì)時(shí)器通常是一個(gè)精密加工過的石英晶體，石英晶體在其張力限度內(nèi)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(gè)寄存器與每個(gè)石英晶體相關(guān)聯(lián)，一個(gè)計(jì)數(shù)器和一個(gè)保持寄存器。

石英晶體的每次振蕩使計(jì)數(shù)器減1。當(dāng)計(jì)數(shù)器減為0時(shí)，產(chǎn)生一個(gè)中斷，計(jì)數(shù)器從保持寄存器中重新裝入初始值。這種方法使得對(duì)一個(gè)計(jì)時(shí)器進(jìn)行編程，令其每秒產(chǎn)生60次中斷（或者以任何其它希望的頻率產(chǎn)生中斷）成為可能，每次中斷稱為一個(gè)時(shí)鐘嘀嗒。
SMD晶振在電氣上可以等效成一個(gè)電容和一個(gè)電阻并聯(lián)再串聯(lián)一個(gè)電容的二端網(wǎng)絡(luò)，電工學(xué)上這個(gè)網(wǎng)絡(luò)有兩個(gè)諧振點(diǎn)，以頻率的高低分其中較低的頻率為串聯(lián)諧振，較高的頻率為并聯(lián)諧振。

具備優(yōu)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(gè)頻率的距離相當(dāng)?shù)慕咏?，在這個(gè)極窄的頻率范圍內(nèi)，晶振等效為一個(gè)電感，所以只要晶振的兩端并聯(lián)上合適的電容它就會(huì)組成并聯(lián)諧振電路。
