If there are a lot of capacitors, how do you tell which circuits are used? Can the resolution type be distinguished by the words marked on the capacitor? See if there is Ac dc? Answer: The ones marked with positive and negative poles can only be used in DC circuits, and the others without positive and negative poles are non-polar. Both AC and DC are available, but they need to be selected according to the withstand voltage level and the type of circuit requirements. Some capacitors have specific model identification, and most of them can be identified according to their appearance. Because the capacitor is not only used for AC and DC purposes, but also according to its dielectric loss. The frequency of use must be selected according to the circuit design requirements. Follow-up: Some capacitors are small in size and have little voltage resistance. Why is their capacity higher than other large-capacity capacitors with high voltage resistance? Does n’t it mean that the volume is large and the capacity is large? Answer: Compared with capacitors of different types, the larger the capacity and the higher the withstand voltage, the larger the volume. Different varieties have different manufacturing processes due to the different thickness of the insulating dielectric material used, and the larger the volume, the larger the capacity. Sometimes there are different manufacturers of the exact same model and specifications, and there will be large differences in different sizes during the production period.
