又一波晶振規(guī)格選型雨直落工程的心坎.選決定一切,當(dāng)然參數(shù)也是很重要的,選對(duì)參數(shù)就等于少費(fèi)苦力.有些時(shí)候?qū)д癫惶私?也成了苦惱的問題.晶振封裝極多,現(xiàn)最小的是2012晶振,排名第二的則是2016晶振,兩個(gè)小體積的晶振不僅有32.768KHZ頻率也有MHZ頻率.其次就是2520貼片晶振,3215晶振,3225晶振,4115晶振,4.8*1.9晶振(簡(jiǎn)稱5020晶振),5032晶振,6035晶振,7050晶振,8045晶振,這些都只是貼片封裝的一些尺寸.插件的就更多了.每種系列的參數(shù)規(guī)格泰河電子都會(huì)一一整理出來供大家參考選型.有些未來的及整的可以聯(lián)系咨詢泰河的工作人員.
