Multilayer Ferrite Chip Beads
CI Series (Large Current)
Features
High density packaging with a pitch of 2.54 mm
（0.1
inch）max. is possible. This series requires less
space and has greater EMI suppression effects.
Different types with the same shape are available.
Excellent in physical properties, such as terminal
strength, flexure strength, soldering resistance and
solderability.
Applicable to both flow and reflow soldering.
High impedance cover wide frequency ranges.
CI series can be used in high current circuits due to
its low DC resistance.
Applications
Computers
and
peripheral
devices,
personal
computers, VCR and cameras.
Noise suppression in digital equipments, car stereo,
car
engines
controllers
and
OA
electronic
instruments.
Communication equipment.
