FNR-10K471 varistor


In general, withstanding surge current is max. Pulse current value which determined by test conditions such as wave-shape, shock times and interval time etc, the change ratio of Varistor Voltage should be less than ±10% of the initial Value. The shock time is the function of wave – shape, amplitude and interval time ,when the amplitude decrease to 50% of the initial, it should be increased to 2 times of the initial in order to keep the life longer, the surge current which is absorbed by the varistor should be less than max. Withstanding surge current.
