Chip Beads(SMD)

For Signal Line

MMZ Series MMZ1608 Type

FEATURES

• Chip bead(impeder), MMZ series offers 7 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.
