SV Series Special Medium Voltage Varistors

Bourns’ SV series of lead style epoxy coated square or rectangular shaped varistors have 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 series varistors are produced with smaller nominal dimensions.

In addition to the standard offering, customers can design a 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, and shape. The dimensions being the function of required electrical parameters and vice versa.
