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.

c Voltage - Current Characteristics

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.
