SV550 K 20 Features Formerly a product +85 C Continuous operating temperature Six model sizes equivalent to standard Low clamping voltage disc varistors Available with straight or crimped leads Smaller nominal dimensions than disc Available in tape and reel packaging for varistors automatic pick-and-place Broad range of current and energy RoHS compliant* handling capabilities SV Series Special Medium Voltage Varistors General Information Additional Information Click these links for more 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 PRODUCT TECHNICAL INVENTORY SAMPLES CONTACT energy capabilities and a low clamping voltage, providing an increased level of protection SELECTOR LIBRARY for the transients expected in telecommunication and AC power networks. Compared to electrically equivalent disc varistors, SV varistors are produced with smaller nominal Agency Recognition dimensions. Standard UL 1449 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 File Number E313168** chosen are: non-standard DC/AC operating voltage, leakage current, clamping voltage, ** Not all rated voltages are UL recognized maximum surge current, energy absorption level, maximum dissipation power as well check the file for details. as shape - the dimensions being the function of required electrical parameters and vice-versa.
