Introduction to E series; a compact and high-performance ZNR
E series features a compact size and high performance that past products failed to achieve, thanks to our original material design and processing techniques.
E series has 1.5 times the capability of the V series.
In this video, we discuss the features and benefits of the E-Series Varistors (ZNR Surge Absorber).
Features of E series
■Compactness: Despite its small size, the E series offers the same surge current withstand capacity as other types.
A ZNR with the same surge current withstand capacity as that of the E series can be replaced with the E series. This
achieves significant component miniaturization.
Surge current withstand capacity
11.5×4.8×14.5 = 800 mm3
15.5×4.8×18.5 = 1376 mm3
21.5×5.2×24.5 = 2739 mm3
10.5×5.1×13.5 = 723 mm3
13.0×5.2×17.0 = 1149 mm3
16.5×5.2×20.0 = 1716 mm3
■Despite having the same shape as other types, the E series offers a higher surge current withstand capacity.
A ZNR with the same shape as the E series can be replaced with the E series. This will enable you to have significantly
increased surge current withstand capacity.
Our original material design and processing techniques have led to the development of the compact and high-performance
ZNR with about 1.5 times the capability of the V series.
Atomic alignment states are made uniform through valence control to increase carriers (electrons), which makes ZnO
grains less resistant, creating a state where current flows easily. Resistance is thus suppressed in a large current
flow area to allow larger current flows. In addition, crystal grains are made uniform in diameter as grain boundaries
are made homogenous by improving the dispersibility of the material. This also contributes to homogenous current flows,
thus allowing large current flows.
