EMI LEADED FILTERS

EMI SUPPRESSION FILTERS

WITH SEMICONDUCTOR SURGE PROTECTION

VFR303 Series

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.
