NTE2V275 MOV 275V RMS Dia=16mm 72 Joules Itm=4500A Clamping Voltage=685V
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.
