Chip Bead Array
CIA Series- CIA31 (3216 EIA1206)
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-magnetic wave noise by increased
impedance, especially by increased resistance at noise frequency.
Four lines in 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
SPECIFICATION
Operating temperature range –25 to +85°C
Storage temperature range –10 to +40°C
