* Add termination material character (T)

Maximum allowable voltage - the maximum sinusoidal RMS voltage or maximum DC voltage which can be applied continuously

E:

Maximum energy - the maximum energy within the varistor voltage change of ±10% when a single impulse of 2m sec. is applied

Maximum peak current - the maximum peak current within the varistor voltage change of ±10% when a single standard impulse

of 8/20µ sec. is applied two times with an interval of 5 min.

Operating temperature - Ambient temperature range when the device is operating

Storage temperature - Temperature range without causing the device any failure
