General Information

The SV series is a series of lead style epoxy coated square or rectangular shaped

varistors with an AC operating voltage ranging from 60 V to 550 V. This series offers both

standard and custom options.

The standard offering consists of square shaped varistors with extremely high current

and energy capabilities and a low clamping voltage, providing an increased level of

protection for the transients expected in telecommunication and AC power networks.

Compared to electrically equivalent disc varistors, SV varistors are produced with smaller

nominal dimensions.

In addition to the standard offering, customers are offered the option to design their

own customized varistor to suit their specific application needs. Parameters free to be

chosen are: non-standard DC/AC operating voltage, leakage current, clamping voltage,

maximum surge current, energy absorption level, maximum dissipation power as well

as shape - the dimensions being the function of required electrical parameters and

vice-versa.
