Chip Beads(SMD)
For Signal Line
Conformity to RoHS Directive
MMZ Series MMZ1608 Type
FEATURES
• Chip bead(impeder), MMZ series offers 6 construction materials.
• 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.
• The products contain no lead and also support lead-free
soldering.
• It is a product conforming to RoHS directive.
APPLICATIONS
Personal computers, CRTs, liquid crystal display panels, printers,
hard disk drives, game machines, cellular phones, etc.

HANDLING AND PRECAUTIONS
• Before soldering, be sure to preheat components. The preheat-
ing temperature should be set so that the temperature difference
between the solder temperature and product temperature does
not exceed 150°C.
• After mounting components onto the printed circuit board, do not
apply stress through board bending or mishandling.
• The inductance value may change due to magnetic saturation if
the current exceeds the rated maximum.
• Do not expose the inductors to stray magnetic fields.
• Avoid static electricity discharge during handling.
• When hand soldering, apply the soldering iron to the printed cir-
cuit board only. Temperature of the iron tip should not exceed
350°C. Soldering time should not exceed 3 seconds.
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.
R material: For wide frequency applications calling for broad
impedance characteristics.
For digital signal line applications calling requiring
good waveform integrity. Impedance values selected
for effectiveness at 10 to 200MHz.
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.
A material: This high-impedance product is based on the imped-
ance frequency characteristics of our Y-material. The
product offers excellent impedance characteristics,
which is greater than 2500Ω, in the vicinity of 100MHz
range (MMZ1608A252B).
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.

• Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific
bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications.
• Please contact our Sales office when your application are considered the following:
The device’s failure or malfunction may directly endanger human life (e.g. application for automobile/aircraft/medical/nuclear power devices, etc.)
• All specifications are subject to change without notice.
