Dual capacitors come in a variety of sizes, depending on the capacitance (measured in microfarads, μF), such as 40 plus 5 μF, and also on the voltage. A 440-volt capacitor can be used in place of a 370-volt, but not a 370-volt in place of a 440-volt. [2] The capacitance must remain within 5% of its original value. [2]

Measuring ESR can be done by applying an alternating voltage at a frequency at which the capacitor's reactance is negligible, in a voltage divider configuration. It is easy to check ESR well enough for troubleshooting by using an improvised ESR meter comprising a simple square-wave generator and oscilloscope, or a sinewave generator of a few tens of kilohertz and an AC voltmeter, using a known ...
Figure 2.Greinacher circuit. The Greinacher voltage doubler is a significant improvement over the Villard circuit for a small cost in additional components. The ripple is much reduced, nominally zero under open-circuit load conditions, but when current is being drawn depends on the resistance of the load and the value of the capacitors used.
They use the FIT specification with 40 °C and 0.5 U R as reference conditions. aluminium electrolytic capacitors are very reliable components. Published figures show for low voltage types (6.3…160 V) FIT rates in the range of 1 to 20 FIT [ 88 ] and for high voltage types (>160 …550 V) FIT rates in the range of 20 to 200 FIT. [ 86 ]
