Miniature Aluminum Electrolytic Capacitors Ripple Current of Miniature Size Aluminum Electrolytic Capacitors Maximum Permissible Ripple Current Diagram 1 Voltage Limitation A polar capacitor can be used, but the peak voltage (VH) applied VH Voltage to the capacitor should not exceed its rated voltage. (Refer to Diagram 1) Current Limitation Ripple current should not exceed the maximum permissible ripple current, as defined in Tables 1 to 4. When current measurement cannot be taken 0 because of the superimposition of more than two frequencies, electrical current Time should be held down to such a level that the surface temperature of the capacitor rises no more than 3C above room temperature.
