Multilayer varistor SV Series

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. There are two groups of these varistors. The first consists of square shaped varistors with extremely high current and energy capabilities and a low clamping voltage, providing an increased level of protection necessary for the transients expected in telecommunication and AC power networks. Compared to electrically equivalent disc varistors, SV varistors come in smaller nominal dimensions. With the second SV series group, the customer is offered the opportunity to design their own optimum varistor to suit their specific application, within the dimensions that are possible. 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.
