FEATURES
• Two sizes: 1.6×0.8×0.6 and 1.6×0.8×0.8mm. Compact bead built
using 5-materials construction.
• Layout of the interior electrode structure has been optimized,
thereby improving high frequency characteristics, decreasing
Rdc, an d lowering he ight.
• Size standardized for use by automatic assembly equipment. No
preferred orientation.
• Either flow or reflow soldering methods can be used due to
electroplating of the terminal electrodes.
• H igh relia b i lity du e to an e ntir e ly m onol ithic s truc tur e .
• Closed magnet ic circui t structure allows high-density in stallation
while preventing crosstalk.
• Low DC resistance structure of electrode prevents wasteful
electric pow e r co ns umption.
APPLICATIONS
Personal computers,CRTs, liquid crystal display panels, printers,
hard disk drives, game machines, cellular phones, etc.

MATERIAL CHARACTERISTICS
B material: T his type is perfectly suited for fast digital signals. By
equalizing R components and X components that
beads possess at a frequency of 5MHz, it is able to
suppress overshooting, undershooting and ringing of
fast digital signals.
R material: For wide frequency applications calling for broad
imped ance characteristics.
For digital signal line applications calling requiring
good waveform integrity. Impedance values selected
for effectiveness at 10 to 200MHz.
S mater ial : St andard type t hat feat ures impedance chara cter ist ic s
similar to those of a typical ferrite core.
For signal line applications in which the blocking region
is ne ar 100 MHz. Impedance v alue s s elect e d fo r ef fec -
tiveness at 40 to 300MHz.
Y material: High frequency range type intended for the 100MHz
region and above.
For signal line applications in which the signal fre-
qu en cy i s fa r fro m th e cu to ff fre qu en cy . Im pe da n ce val-
ues selected for e ffectivenes s at 80 to 40 0 MHz.
D ma teria l : For a ppl ic atio ns calling for low in se rti o n lo s s at lo w fr e -
quencies and sharply increasing impedance at high
fr equen cies . Desi gned fo r hi gh impeda nce at hi gh f re-
quencies (200 to 500MHz) for signal line applications.
