Development of high-voltage varistor composition allows application to AC100Vrms and AC200Vrms power circuits, which has
not been materialized by conventional multilayer chip varistors hitherto.
• Applicable to AC100Vrms and AC200Vrms power lines.
• Applicable to high voltage (varistor voltage: 470 V max.).
• The zinc oxide material ensures high reliability with excellent nonlinearity and response.
• Compact and available to be surface mounted.
RoHS Compliant.
Features
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.
