How are ESR and tan δ related?
Tan δ, or dissipation factor, is a property of a capacitor used to express energy loss within the capacitor. The higher the tan δ, the more energy is lost.
Tan δ is used to calculate ESR. The formula to calculate ESR is ESR = tan δ * Xc or tan δ / (2πFC)
Do aluminum electrolytic capacitor voltages change with temperature?
The rated voltage of an aluminum electrolytic capacitor does not change based on temperature. The capacitor’s rated voltage can be applied across its entire specified temperature range.
Does applied voltage change the capacitance of an aluminum electrolytic capacitor?
No. The capacitance of an aluminum electrolytic capacitor does not change with applied voltage.
How long can aluminum electrolytic capacitors be stored on the shelf?
Aluminum electrolytic capacitors can be stored without voltage being applied to them at 5 °C to 35 °C for up to two years after the date of manufacture. After two years the parts need to be checked to verify they have not drifted out of specification. If they have drifted out of specification, their shelf storage life can be extended by performing a voltage treatment.
