MULTILAYER CHIP VARISTORS [ CVG30A ¥ 40A Series ]
CHIP VARISTORS
The multilayer chip varistor, CVG Series, is a surge absorbing ceramic varistor developed for high-density surface mounting.
The compact varistor has a multilayer structure for high maximum peak current.
a Features
• Very large maximum peak current in compact sizes.
• The zinc oxide material ensures high reliability with excellent nonlinearity and response.
• It is possible to supply in embossed taping best for automatic mounting.
• RoHS Compliant.
a Applications
Protection of various semiconductor elements from overvoltage. Protection of various types of equipment from inductive lightning surge. Absorption of switching surge and electrostatic surge for relays, horns, and motors.
Operating temperature range : –40°C~+125°C
