Features
· Flame-resistant
Suppress combustion and smoking after a malfunction caused by larger
surge than the specified value
· Environment-friendly materials
Adopts newly developed halogen-free resin mold and the Pb-free plated
lead wires
· High reliability
Greatly improved heat-cycle resistance
· Small size and high performance
· Ratings and specifications are same as the conventional ENE series.

1
The waveform of the maximum DC applied voltage is flat.
When a ripple voltage as from a rectifier source is applied, make
sure that the peak voltage is within the Vdcm rating.
The AC applied voltage (50/60Hz) is a sine waveform.
When waveform distortion is extensive, make sure that the peak
voltage is less than 2 times the Vacm rating.
Energy Wtm
Transient energy rating are given in the Wtm column in Joules (Watt-
second). The rating is the maximum allowable energy of a single 2ms
square-waveform impulse current continuously applied.
Energy ratings are based on a shift of Vnom of less than ±10% of
the initial value.

Transient peak current (Itm)
The peak current rating, Itm, is based on 8/20μs test impulse wave
form. This peak current is the maximum peak current at which the
nominal varistor voltage shift dose not exceed ±10% when the test
impulse is applied twice at a 5 minute interval.

Nominal varistor voltage: Vnom
Indicates the varistor terminal voltage measured with 1mA DC
applied. 05A type 0.1mA DC

5
Maximum clamping voltage: Vc
Indicates the peak terminal voltage measured with 8/20μs impulse
current applied.
