       Aluminum Electrolytic capacitorWhat are the key points in selecting the rated voltage of? The capacity and withstand voltage marked on the aluminum Electrolytic capacitor body are very important and are the most basic content for selecting capacitors. In actual capacitor selection, larger capacitors should be used for areas with fast current changes, but it is not necessarily better to have larger capacities. Firstly, as the capacity increases, the cost and volume may increase. Additionally, the larger the capacitor, the greater the charging current and the longer the charging time. These are all considerations to consider in practical application selection.

Rated working voltage: The maximum DC voltage that a capacitor can withstand when operating reliably for a long time within the specified working temperature range. In AC circuits, it is important to note that the maximum AC voltage applied cannot exceed the DC operating voltage of the capacitor. The commonly used fixed capacitor working voltages include 6.3V, 10V, 16V, 25V, 50V, 63V, 100V, 200V, 250V, 400V, 450V, 475V, 500V, 600V, and 630V. The actual voltage that a capacitor must withstand in a circuit cannot exceed its withstand voltage value.

In the filtering circuit, the withstand voltage value of the capacitor should not be less than 1.42 times the AC effective value. Another important issue to note is the operating voltage margin, which should generally be above 15%.

Allowing the rated voltage of capacitors to have more margin can reduce internal resistance, reduce leakage current, reduce loss angle, and increase service life. Although the use of 50V aluminum Electrolytic capacitor with 48V working voltage will not cause problems in a short time, the service life may be reduced if it is used for a long time.
