DESCRIPTION
Walsin Multilayer Chip Varistor is a family of Transient Voltage Surge Suppression products.Today , electronic
circuits are becoming smaller and more sentive to external interference. Walsin Multilayer Chip Varistor is
designed to protect components from destruction of transients and ESD(Electronic Static Discharge). The wide
operating voltage and energy rage make Walsin Multilayer Chip Varistor suitable for numerous applications on
I/O protection , Vcc protectiion , Keyboard protection , LCD protection , Sensor protection…etc. The Walsin 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.
