EMC Components
Ferrite Beads
SMD
FEATURES
• 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.
• High reliability due to an entirely monolithic structure.
• Closed magnetic circuit structure allows high-density installation
while preventing crosstalk between circuits.
• Low DC resistance structure of electrode prevents wasteful
electric power consumption.
• It is a product conforming to RoHS directive.
APPLICATIONS
PCs, CRTs, liquid crystal display panels, printers, hard disk drives,
game machines, cellular phones, etc.

MMZ Series MMZ1005 Type
Size: JIS/IEC 1005, EIA 0402
MATERIAL CHARACTERISTICS
B material: This 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.
S material: Standard type that features impedance characteristics
similar to those of a typical ferrite core.
For signal line applications in which the blocking region
is near 100MHz. Impedance values selected for effec-
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-
quency is far from the cutoff frequency. Impedance val-
ues selected for effectiveness at 80 to 400MHz.
D material: For applications calling for low insertion loss at low fre-
quencies and sharply increasing impedance at high
frequencies. Designed for high impedance at high fre-
quencies (200 to 500MHz) for signal line applications.
F material: This new product inherits the characteristic of our D-
material, namely its sharp impedance rise time, and its
impedance peak frequency has been shifted higher
into range. The product offers excellent noise suppres-
sion from 600MHz to as high as in the GHz range.
