EMI LEADED FILTERS
EMI SUPPRESSION FILTERS
VARISTOR-CAPACITOR
The DSS710 uses a capacitor element which provides the varistor
function. This varistor-capacitor not only works
as a bypass
capacitor but also lets high-voltage surges flow to ground.
The varistor-capacitor used in the DSS710 has a 3-lead structure,
so that its high frequency functions are substantially better than
those of conventional capacitors. Furthermore, it is combined with
ferrite bead to form a T-shaped filter circuit that most effectively
suppresses EMI.
The DSS710 efficiently removes fast-rising transients and
high-frequency EMI above 50 or 60 MHz which conventional
capacitors and varistor-capacitors are incapable of removing.
Varistor-capacitors are used even where conventional EMI-filters
fail. They are self-healing and effective in circuits having
500-600V impulses.
