VFS9V

c Outline

o EMIGUARDr eliminates both surge noise and EMI noise

applying some unique design like the use of dielectric

varistor material to a 3 terminal capacitor.

o Effective when high frequency noise and high voltage

surge suppression are required, and also in situations

when surging starts at extremely high speeds. This type

of surging cannot be eliminated with general type

varistors.

Type of Filter

No filter

Three-terminal capacitor is

used to suppress the surge.

EMIGUARD

r is used to

suppress the surge. (
