SMD capacitor are widely used around us and have universal uses. Most people who do not know SMD capacitor do not know how to judge the main parameters of SMD capacitor. Next, Pingshang Electronics will explain to you.
Additional working voltage: The power capacitor can work stably for a long time in the power circuit, and the larger AC voltage accepted is called the withstand voltage.
Insulation resistance: used to explain the magnitude of leakage. The insulation resistance of electrolytic capacitor is relatively small. In contrast, the larger the insulation resistance, the better, and the leakage is also small.
Loss: under the action of an electric field, the energy consumed by the SMD capacitor in a unit time of heating.
Temperature coefficient: within a certain temperature scale (the lower the temperature coefficient, the better), the relative change value of the capacity for every 1°C change in temperature.
Frequency characteristics: The main electrical parameters of the SMD capacitor change with the frequency of the electric field.
Reminder: The model of the SMD capacitor is different from the application parameters, so please choose the SMD capacitor according to the actual application parameters.
