Voltage. A capacitor will have a marked voltage indicating its acceptable peak voltage, not its operational voltage. Therefore, you can select a capacitor with a voltage rating at or above the original capacitor. If you''re using a 370 volt capacitor, a 370 or 440 volt one will work, though the 440 volt unit will actually last longer.
