Short Life of Oil CAP only 250 Hours??


Here is what I have got from one of the oil cap website:

"Lifetime test: 250 hours at the maximum category temperature and 2 x Un, according to IEC 80 § 21."

Does it mean that you have to replace them so often? 250 hours is nothing in audio. I know it could be longer if it 's running lower than the spec., but not sure by how much.

Any comment on this?

Such a spec is only for the maximum temperature the part is rated for, kind of a 'failure' rating - not the life of the part for the recommended temperature range at which it is intended to be used. That temp will be significantly lower, and the resulting part life much longer. See if you can do a little more research - from what I've seen, there is often another projected lifetime rating given for a 'normal' average temperature.
