The current passed. 3.20 Capacitor type typeofcapacitor When capacitors have similar structures, the same structure, the same rated voltage, the same climate category and the same operating mode When considered, it is considered to be of the same type. Capacitors of the same type can only differ in their rated capacitance and size. Comparison between the lead terminal and the mounting member Small differences are allowed. Note. The same structure includes the same dielectric material, media thickness, and housing type (metal or plastic). 3.21 Capacitor model modelofcapacitor When the capacitors are of the same structure and have the same functional and dimensional characteristics within the tolerances and are therefore interchangeable, they are considered The same style. 3.22 Safety rating classofsafetyprotection The degree of safety protection is indicated by one of the following four codes and is marked on the capacitor. 3.22.1 (S0)Safety Protection Level (S0)classofsafetyprotection This level of safety indicates that this type of capacitor has no special fault protection.
