The raw materials and firing process of 1.SMD capacitor determine that it is inconvenient to have the capacity value mark on its body at present. This is one of the most obvious differences among patch resistance, tantalum capacitor and aluminum electrolytic capacitor except appearance. Therefore, it is clear that accurate nominal capacity information cannot be simply obtained from the patch capacitor body.
2. You can mail the capacitor sample to the technical department of SMD capacitor manufacturer, and the manufacturer will use the electronic component testing laboratory to help you test the nominal capacity value.
