Walsin Technology Corporation
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.
FEATURES
1. Multilayer fabrication technology
2. -55℃to 125℃ operating temperature Range
3. Operating voltage range VM(DC) at 5.5V ~ 85V
4. Able to withstand ESD test of IEC-61000-4-2
5. Bi-directional clamping characteristic
APPLICATIONS
1. Protection of cellular phones, PDA, High Speed Data Line…etc.
2. ESD Protection for components sensitive to IEC 61000-4-2, Provides Circuit Board Transient Voltage
Protection for Transistors.
3. Protection of Video & Audio Ports.
