EMI LEADED FILTERS
EMI SUPPRESSION FILTERS
VARISTOR-CAPACITOR
DSS706 Series
The DSS706 Varistor-Capacitor is a three-terminal filter which
suppresses noise emission from electronic equipment while
controlling incoming surges of static electricity. Its small size
enables 2.5mm pitch mounting.
APPLICATIONS
Elimination of noise and protection of semiconductors in office
automation equipment, including computers, peripheral equipment,
copy machines, and communication terminals.
FEATURES
ꢀꢀ
Protects circuits from electrical surges and acts as a filter for
signal lines.
ꢀꢀ
Effectively suppresses high-frequency noise from signal lines.
(Performance equivalent to conventional three-terminal capacitor.)
ꢀꢀ
Small size enables it to be mounted at 2.5mm pitch.
Three-terminal structure leads to superior high-frequency
characteristics.
ꢀꢀ
Built-in ferrite bead provides excellent EMI suppression.
