Chip Beads

For Signal Line

MMZ Series MMZ2012

FEATURES

• Chip bead(impeder), MMZ series offers 4 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

Removal of signal line noises of cellular phones, PCs, note PCs,

TVs, TV tuners, STBs, audio players, DVDs, DSCs, DVCs, game

machines, digital photo frames, car navigation system, PNDs, 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.

• 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

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.

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.

The device’s failure or malfunction may directly endanger human life (e.g. application for automobile/aircraft/medical/nuclear power devices, etc.)

• 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.
