Aker音叉晶體CTS3-32.768-9-20-R為何開創(chuàng)新的精度標準?在這一突破之前，所有的鐘表都是純機械運轉(zhuǎn)的。通過安裝石英晶體和使石英振蕩的相應(yīng)能量源，首次引入了電子元件。這確實奏效了:新款石英表的走時比純機械手表精確得多。
但是石英晶體實際上實現(xiàn)了什么功能呢？簡而言之，高質(zhì)量石英晶體確保手表“知道”一秒持續(xù)多長時間。這是通過產(chǎn)生恰好1赫茲的頻率來實現(xiàn)的。赫茲是頻率的常用測量單位。它表示周期信號中每秒重復(fù)過程的次數(shù)；在這種情況下，秒針在表盤上前進一個位置。
32，768赫茲音叉無源晶體的唯一標準頻率來自哪里？要理解這一點，你必須知道石英晶體的頻率取決于它的形狀和大小。一個自然頻率只有1赫茲的石英會如此之大，它更適合“大本鐘”鐘樓，而不是手表。顯然，從生產(chǎn)和使用的角度來看，這是相當不切實際的，所以有一個特殊的技巧。Aker公司匠心締造石英晶體編碼CTS3-32.768-9-20-R，Crystal，無源晶振，頻率為0.032768MHz，頻率公差為±20ppm (Tol) ，負載電容為9pF，腳位為2-Pin，SMD，T/R.
