CV Series — Low and Medium Voltage Leaded Varistors
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 from 5 to 20mm and feature a wide range of AC operating
voltages from 50V to 680V.
Features
• AC operating voltage (Vrms) from 50V to 680V
• DC operating voltage (Vdc) from 65V to 820V
• Broad range of current and energy handling capability
• For RMS voltages
≤40V
see ZV leaded series
• 5 model sizes available from 5mm to 20mm
• UL, CAC, CEDD approved
• +85°C continuous operating temperature
