Multilayer Chip Varistor
MCVZ0402 Green Material Series
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 rage
make Multilayer Chip 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 lead less , surface mount form , compatible with modern reow and
wave soldering procedures.
Features:
• Multilayer fabrication technology
• -55°C to +125°C operating temperature Range
• Operating voltage range Vm(dc) at 5.5V to 18V
• Able to withstand ESD test of IEC-61000-4-2
• Bi-directional clamping characteristic
Applications:
Protection of cellular phones, PDA, High Speed Data Line etc.
ESD Protection for components sensitive to IEC 61000-4-2, provides circuit board transient voltage protection for transistors.
Protection of Video & Audio Ports.
