Large Current VFS9V Series
c Features
VFS9V series is designed for surge protection of
the power supply. It protects electric circuits from
surge such as static electricity and suppresses EMI
noise. Its large capacitance value enables high
insertion loss for EMI noise.
c Applications
For circuit protection and noise suppression in
electronics equipment such as computers and DC motors,
and in electronics systems installed in cars such as
car audio equipment and engine controllers.

Rated current is 7A for bulk type and 6A for taping type.
Rated current of taping type is 6A because the diameter of the lead is 0.6mm and its lead layout is the in-line type.
Please refer to Part Numbering for Type and Length of Lead.
