   Description

         Multilayer chip Varistor is a family of Transient Voltage Surge Suppression products. Today,

    electronic circuits are becoming smaller and more sensitive to external interference. 

          Multilayer chip Varistor is designed to protect components from destruction of transients and

    ESD (electronic static discharge). The wide operating voltage and energy range make Multilayer

    Varistor suitable for numerous applications on I/O protection, Vcc protection, Keyboard protection,

    LCD protection, Sensor protection…etc. 

          The chip Varistor is manufactured by Multilayer fabrication technology providing excellent voltage

    clamping ability and is supplied in leadless, surface mount form, compatible with modern reflow 

    and wave soldering procedures.
