S4008FS21 Overview

Current RMS is the average strength of the current without regard to its direction, and the current's RMS current (Irms) is 8A.For a device to function normally, it is important that the RMS on-state current remains below 8A.Electrical, electromagnetic, and electronic devices require a holding current (hypostatic) to remain in the 'ON' state, and the current may be 6mA.In order to determine the effectiveness of insulation on conductors, leakage current can be measured and its maximum leakage current can be set as 0.1mA.
