   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.
