4PIN光耦EL817命名/品名编码方式:
EL817X(Y)(Z)-FVG
说明:
EL是Everlight的简写标识
X = Lead form option (S, S1, S2, M or none)电极脚的规格,Sx表示贴片方式,M表示宽脚位0.4 "即10.0mm
Y = CTR Rank (A, B, C, D, X , Y or none)电流放大倍率,例如C表示CTR为200~400%
Z = Tape and reel option (TA, TB, TU, TD or none).包装方式,包装管或者贴片编带的具体方式
F = Lead frame option (F: Iron, None: copper)电极引脚的材质,F为特合金,不标注表示铜合金
V = VDE safety (optional).德国的VDE安规认证
G = Halogens free符合卤素管制要求

●光电耦合器/光耦电流传输比CTR,指的是输出电流与输入电流之比,即输出电流IC与输入电流IF的百分比,通常用百分数来表示。公式:CTR=IC/ IF×100%,Everlight亿光光电耦合器4Pin插件晶体管输出光耦EL817的CTR通常为50~600%细分等级为:
测试条件:IF = 5mA ,VCE = 5V
