1.34S metal oxide varistor (MOV), with epoxy resin
2. Diameter and thickness is controlell effectively within the design scale.
3.Peak current is reached the world leading level. It can afford 8/20us impulse, peak current Imax 40kA punch 2 times.
4.Thermal stability. Soldering thermal cutoff member with 145 degree, the cutoff time is no less than 5 senconds under 1A current; the cutoff time is 3-5 seconds under 1.5A current.
5.Energy absorption capacity, applied 2ms impulse, impulse current is 600A, the max. energy absorption capacity is more than 1000J.
6.Life time. Applied 83% varistor voltage at 85 degree to accelerate aging. The lifetime characteristic curve is good, varistor voltage change rate is less than +/-10%
7.power frequency withstand. Applied 1.2 tims electric load rate, tested for 5 minutes, the varistor is good, the varistor voltage change rate is less than +/-10%.
8.Stability. To exposure in the air for one week, varistor voltage and leakage current is less than |+/- 10%, product performance stable.
