Hi All,
Do Electrolytic capacitors suffer from permanent damage / performance degradation / rated life degradation - if they are subjected to short ( few seconds) of reverse voltage.
Background: I have a PCB that has electrolytic caps on the input and there is no reverse protection on the boards and there is no provision to add them at this time. If a user accidentally connects the input power with reverse polarity for short duration (enough to see the board not powering up) and then connecting again properly! How will it affect the electrolytic capacitors? The power supply voltage is 24V and the ECAP is 470uF / 50V.
