Chip Bead Array; CIA Series

For EMI Suppression

Feature

•Four

lines by one chip

•Perfect

shape for automatic mounting, with no directionality.

•Excellent

solderability and high heat resistance for either flow or

reflow soldering.

•Closed

magnetic circuit configuration with no cross-talk which is

suitable for high density PCBs.

Application

•EMI

prevention in Notebook PC, LCD and car navigation

•Ideal

for dealing with line noise from multiple signals such as

in computer buses.

The CIA Series is an array of ferrite beads used for EMI suppression filters.

This series is often used for high density Printed Circuit Boards to save the space and cost.

It suppresses electro-magentic wave noise by increased impedance, especially by increased resistance at noise frequency.
