This technical column describes the basic facts about capacitors. This lesson describes the voltage characteristics of electrostatic capacitance. The phenomenon where the effective capacitance value of a capacitor changes according to the direct current (DC) or alternating current (AC) voltage is called the voltage characteristics.
The Working Voltage is the second most important characteristic of a capacitor. It provides information about the maximum AC or DC voltage that we can apply to the capacitor without its failure. The working voltage is usually marked on the body of the capacitor. It is typically the DC working voltage of the capacitor.
AC voltage characteristic refers to the phenomenon where the effective electrostatic capacitance changes (increases or decreases) when AC voltage is applied to a capacitor.
DC and AC voltage values are usually not the same for a capacitor as the AC voltage value refers to the r.m.s. value and NOT the maximum or peak value which is 1.414 times greater. Also, the specified DC working voltage is valid within a certain temperature range, normally -30°C to +70°C.
