*1 When rated current is applied to the products, inductance will be within ±30% of initial inductance value range.
*2 When rated current is applied to the products, temperature rise caused by self-generated heat shall be limited to 40°C max.
*3 As shown in the diagram below, derating is applied to the rated current based on the operating temperature.
