In another thread a forum member said that in order for electrolytic capacitors to maintain their properties, their voltage ratings should not exceed more than twice the voltage expected across them, also allowing for any spikes. Aluminum electrolytic capacitors (the most common kind) use aluminum oxide as the dielectric.

To reform the capacitor, the normal method is to apply the working voltage for the capacitor through a resistor of around 1.5 k ohms, or possibly less for lower voltage capacitors. Whereas electrostatic capacitors are specified for test voltages at 150…250 % of the rated voltage, specifications for electrolytics state a surge voltage, vs, usually 110⋅⋅⋅115 % of vr.

This implies an aluminum capacitor whose nominal capacitance is 47µf is expected to have a value between 37.6µf and 56.4µf. The thickness of the oxide is only nanometers on low voltage caps.

Both Sides Of The Capacitor Are Moving Up And Down In Voltage At The Same Time, So The Voltage Across The Capacitor Is Close To 0 V, Even While The Voltage Of The Capacitor Relative To Ground Swings All Over The Place.

They are made with capacitance values from 0.1 μf to 2.7 f [24]. The applied voltage to an electrolytic capacitor should be approximately equal to the voltage rating of the electrolytic. The problem in your circuit that causes it to not work at less than 7v is that you are using a 12v relay as seen here.

Aluminum Electrolytic Capacitors (The Most Common Kind) Use Aluminum Oxide As The Dielectric.

For most practical purposes electrolytic capacitors can be considered to not have a minimum voltage rating. Voltage rating is the operating voltage of the capacitor and it is measured in volts. They can only be used for dc voltage.

Whereas Electrostatic Capacitors Are Specified For Test Voltages At 150…250 % Of The Rated Voltage, Specifications For Electrolytics State A Surge Voltage, Vs, Usually 110⋅⋅⋅115 % Of Vr.

Reversing the polarity of the capacitor or applying a voltage higher than the maximum rated working voltage of 1 to 1.5 volts can cause the dielectric to be destroyed and thus damage the capacitor. To reform the capacitor, the normal method is to apply the working voltage for the capacitor through a resistor of around 1.5 k ohms, or possibly less for lower voltage capacitors. The aluminum oxide is a thin layer formed by anodizing aluminum foil.

Each Capacitor Comes With A Working Voltage, And The Standard Values Are 100V, 250V, 400V, 1000V, 1600V, And Etch.
