Can an electrolytic capacitor withstand 0.1 V reverse polarity?
&quot;Can an electrolytic capacitor withstand 0.1V reverse polarity?&quot;
If you query e.g. technical documents of a well known manufacturer like vishay:
Reverse Voltage UrevA reverse polarity of up to 1.5 V is permissible.

Edit:
German Wikipedia states, a reverse voltage should not be applied for longer times (constantly), also not in case of AC voltage. negative voltages cause a current flow which due thermal spots might damage the oxid layer (with short circuit as a result.)
given the OP's question is still a factor 10 or more away from the mentioned max values, I still would consider it OK - also there is a 100k resistance so current should be limited.
