9 / 22 page ![]() CG01-I 255 EMI LEADED FILTERS EMI SUPPRESSION FILTERS WITH SEMICONDUCTOR SURGE PROTECTION The VFR303 Series is an EMI suppression filter with a built-in varistor function designed to protect semiconductors, such as C-MOS and TTl, from ESD surge rushes. The VFR303 series works well as EMI suppression filter. FEATURES s Absorbs ESD surges, provides IC protection. s Excellent signal line EMI suppression filter. s Thin and low height enables high density mounting. APPLICATIONS Elimination of noise and protection of semiconductors in office automation equipment, including computers and their peripheral equipment, copy machines, and communication terminals.
