USB Series Varistor Low Capacitance Multilayer Varistors GENERAL DESCRIPTION USB Series varistors are designed to protect the high speed data lines against ESD transients. They have very low capacitance and fast turn on times that make this series ideal for data and transmission lines with high data rates. The unique design enables these devices to meet the rigorous testing criteria of the IEC 61000-4-2 standards. New and improved manufacturing process has created these USB series to be one of the best plated varistors in the market today.
