| Subject: | Re: RotaxEngines-List Digest: 8 Msgs - 09/25/18 |
In answer to Hugh McKay's question about the working voltage of an electrolytic
capacitor, I always want a safety margin on electolytics. I have had 100 V wkg
electrolytics blow at 100 V, etc., particularly when they have been in use for
a while. I always want a safety factor of 2 at least on electrolytic
capacitors. I would never put a 12 V wkg electrolytic in a 12 V circuit. Can
save you grief!
