32.768K晶振最初在日本開(kāi)始它的大量發(fā)展，并形成全球之勢(shì)。人們利用晶體的獨(dú)特物理特性，加工成一個(gè)標(biāo)準(zhǔn)的時(shí)鐘晶振。從而應(yīng)用到各種電子行業(yè)，給電子行業(yè)帶來(lái)了一個(gè)歷史的變革；隨著人們技術(shù)水平的提高，晶振的精度和性能越來(lái)越高,體積也越來(lái)越小，有很多的IC集成電路公司己將這小小的晶振放在里面，更加的精密度.

日本進(jìn)口愛(ài)普生晶振FC-12M，是一款32.768kHz晶振，小體積尺寸2.0x1.2mm兩腳貼片晶振，無(wú)源晶振，石英晶體諧振器，具有超小型，輕薄型，耐熱及耐環(huán)境特性，適用于鐘表電子，智能手機(jī)，平板電腦，智能門鎖，儀器儀表，汽車電子，醫(yī)療設(shè)備等，質(zhì)量穩(wěn)定，品質(zhì)優(yōu)越，深受廣大客戶信賴.

FC-12M無(wú)源晶振編碼X1A000021001000是一款32.768k時(shí)鐘晶振

32.768K是一款實(shí)時(shí)時(shí)鐘晶振，它的作用是可以產(chǎn)生時(shí)序電路基準(zhǔn)信號(hào)。而之所以選用32.768K是因?yàn)樗?的15次冪，是因?yàn)榭梢院芫_的得到一秒的計(jì)時(shí)。不僅如此，包括所有的實(shí)時(shí)時(shí)鐘晶振一般都是32.768k或其倍頻。貼片32.768K晶振的負(fù)載電容都是12.5pF。常用32.768K時(shí)鐘晶振的電子產(chǎn)品有智能手機(jī)、智能手表、安防和可穿戴設(shè)備等等。也還有很多生活類、工業(yè)類電子也會(huì)常用到這款頻率的進(jìn)口晶振.
