    Components effective against electromagnetic wave noise as well as electrostatic discharge of signal lines of mobile phones etc. have been required to be more compact, more effective for suppressing noise as well as to improve quality of transmission signal waves. To meet the market demand, Panasonic Electronic Devices Co., Ltd. has developed the chip-type EMI/ESD filter effective against both electromagnetic wave noise and electrostatic discharge with a single compact component (0805 size: (L) 2.0 mm(W) 1.25 mm(H) 0.65 mm), first in the industry.

    [Features]


    1. EMI filters and varistors are built in a single package, first in the industry(*1), suitable for measures for reducing electromagnetic wave noise as well as for suppressing electrostatic discharge of signal lines.
      EMI filter (4-circuits) and varistors (4-elements) are built in a 0805-sized package.
    2. Distributed-constant circuit design, offering noise reduction effective in a wider frequency band
      Cut-off frequency
      EZJL217001: 170 MHZ to 6 GHz
      EZJL228001: 280 MHz to 6 GHz
    3. Excellent pulse-response characteristics, offering high-quality of signal transmission waves
      Signal pulse: 25 MHz (Typ.)
    4. Excellent effect for suppressing electrostatic discharge and high reliability
      Static electricity voltage: 8 kV

    (*1) Our investigation of the "noise suppression components" and the " static electricity suppression components" as of February 21, 2006


    [Applications]

    Measures for suppressing electrostatic discharge and reducing noise of signal lines of mobile phones, PCs, AV equipment, etc.
