4PIN光耦EL817命名/品名編碼方式：

EL817X(Y)(Z)-FVG

說明：

EL是Everlight的簡寫標(biāo)識

X = Lead form option (S, S1, S2, M or none)電極腳的規(guī)格，Sx表示貼片方式，M表示寬腳位0.4 "即10.0mm

Y = CTR Rank (A, B, C, D, X , Y or none)電流放大倍率，例如C表示CTR為200~400%

Z = Tape and reel option (TA, TB, TU, TD or none).包裝方式，包裝管或者貼片編帶的具體方式

F = Lead frame option (F: Iron, None: copper)電極引腳的材質(zhì)，F(xiàn)為特合金，不標(biāo)注表示銅合金

V = VDE safety (optional).德國的VDE安規(guī)認(rèn)證          

G = Halogens free符合鹵素管制要求

●光電耦合器/光耦電流傳輸比CTR，指的是輸出電流與輸入電流之比，即輸出電流IC與輸入電流IF的百分比，通常用百分?jǐn)?shù)來表示。公式：CTR=IC/ IF×100%，Everlight億光光電耦合器4Pin插件晶體管輸出光耦EL817的CTR通常為50~600%細(xì)分等級為：

測試條件：IF = 5mA ,VCE = 5V

B和C為常用的CTR等級規(guī)格，市面上較多客人選用
