PIN CONFIGUTION
优势替代
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
