for Large-Current VFS9V Series
■ Features
The VFS9V series is designed for surge protection of
power supply line. It protects electric circuit from
surges such as static electricity and suppress EMI
noise. Its large capacitance value enables high
insertion loss for EMI noise.
■ 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.
