The Amotech AVLC18S02015 MULTILAYER CHIP VARISTOR is a component which acts as a nonconductor on the circuit in normal circumstances. When overvoltage is loaded, it becomes a conductor which diverts over-current from circuits to ground at critical voltage level.The Amotech AVLC18S02015 MULTILAYER CHIP VARISTOR shows a non-linear V-I behavior similar to Si semiconductor. It has high resistance in normal situation but becomes drastically conducting at critical over-voltage level. The Amotech AVLC18S02015 MULTILAYER CHIP VARISTOR normally acts as a nonconductor, but in case overvoltage is loaded, it becomes conductor that diverts current away from circuits to ground protecting equipments. Fig 1 shows how varistor works and protection effect against ESD in short period of time.Fig 1 shows how varistor works and protection effect against ESD in short period of time.
