CV Series – Low & Medium Voltage Leaded Varistors
Single Layer Technology
Varistor Plus
Description
The CV Series of transient surge suppressors are disc-shaped varistors that can be operated
continuously in low and medium voltage electronic circuits, as well as across AC power lines.
Due to their radial lead construction, these components require very little mounting space. They
are available in five model sizes: 5 mm, 7 mm, 10 mm, 14 mm and 20 mm and feature a wide
range of AC operating voltages from 11V to 550V.
Features
• Operating voltage range V

........14V to 745V
• 5 model sizes available.......5 mm, 7 mm, 10 mm, 14 mm, 20 mm
• Broad range of current and energy handling capabilities
• +85°C continuous operating temperature
• Available in tape and reel for automatic pick and place
