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.
