Hi to all. How can you tell if a cap is a low ESR type. I have a lot of electrolytics around , but I am not sure if any of them are low ESR types. Is there a paticular marking that a low esr cap would have. Cheers. Rob
You measure it and/or read the data sheet. It depends on what ESR you need. A "low ESR" cap may not be low enough for your given application, and alternatively a "normal" cap may already have low enough ESR for your application.
There is no standard symbol or marking. Some are marked in some way to make make it fairly obvious, but many aren't.
Thanks for YOUR reply. The caps are used in an SMPS. I have another post about that in this group. The person I got them from said they were a low esr type ,but I was wondering how I could tell , apart from measuring them with an ESR meter. Pity there are no markings to say. Thanks Rob
