Chip Bead ; CIB/CIM Series
For EMI Suppression
Feature
•Smallest
beads suitable for surface mounting
•Perfect
shape for automatic mounting, with no directionality.
•Excellent
solderability and high heat resistance for either flow or
reflow soldering.
•Monolithic
inorganic material construction for high reliability.
•Closed
magnetic circuit configuration avoids crosstalk and is suitable
for high density PCBs.
Application
•High
frequency EMI prevention application to computers, printers,
VCRs, TVs and mobile phones.
The CIB/CIM Series are used for EMI suppression filter. These beads suppress electro-magnetic wave noise by
increased impedance, especially by increased resistance at noise frequency.
CIB Series
The CIB Series is composed of mono-layer internal conductor that allows low impedance and low DC resistance.
CIM Series
The CIM Series display high impedance because it is composed of a multilayered internal conductor and has excellent
attenuation characteristics for wide band frequencies.
