? AC 電壓斷電后通過放電電阻對 X 電容放電
? 功率損耗<5mW@230VAC
? X 電容容值靈活調(diào)節(jié)，簡化 EMI 濾波電路設(shè)計
? 自供電，無需外部偏置
? 兩端子結(jié)構(gòu)，滿足安規(guī)標(biāo)準(zhǔn)
? 內(nèi)部限制最大放電電流
PIN CONFIGUTION
優(yōu)勢替代
FEATURES
? Disconnect series discharge resistors from
L-N when AC voltage is applied
? Connect series discharge resistors with L-N
to discharge the X capacitor when AC
voltage is unplugged
? Supplied by AC voltage directly and doesn’t
need external bias
? Meets safety standards for use before or
after input fuse
? No external ground pin leads to high
common mode surge immunity
? 1000V internal JFET inside leads to high
differential surge immunity
? >4mm creepage on package and PCB
? Compliant to IEC 60950-1
