NTE524V13 MOV 135V RMS Dia 23mm 72 Joules Itm 6500A Clamping Voltage 355V
 
The NTE Metal Oxide Varistors feature a barrier layer that gives the user fast response time. These devices have a high transient current handling capability when high voltage is applied. Static resistance is, however, very high under low voltage conditions, permitting low standby drain currents.
