_{Idc1: Current based on inductance variation(Current when inductance decreases by 10% of the initial value)}
_{Idc2: Current based on increasing product temperature(Current when temperature of the product reaches +30°C)}
_{Between Idc1 and Idc2, the smaller of the two will be made the rated current.}
