KOA Speer NV73DS Series
Load Dump Metal Oxide Varistors
KOA Speer NV73DS Series Metal Oxide Varistor is a multilayer, 40-joule load dump varistor that absorbs surge voltage that occurs from the inductive loads of motors and relays to protect electronic components. The NV73DS series load dump metal oxide varistors from KOA feature symmetrical non-linearity V-I characteristics ideal for maximum absorption of both positive and negative surges and have a high resistance to cyclic temperature stress. These varistors meet load dump surge test for JASO and are AEC-Q200 qualified. NV73DS specifications include voltage ranges from 20 to 45 V1mA, maximum clamping voltages between 40 and 60 V1A, and operating temperature range from -40ºC to +125ºC.
