Capacitor question

Post by orthophonio on Thu Jan 24, 2013 9:59 pm

I know this is a 'radio parts' forum but this question is related to an RCA EY-4 phonograph. I'm sure the part is used in radios as well.

I am about to order the capacitors so I can recap the amp and there's one with a value of .01uf +10% 200volts. What's the '+10%' all about and what capacitor would I order that would be the same value.

Thanks-
Scott

Hi Scott it simply means 10 percent margin of error .
most of just order 630 volt replacements

Thanks jukeboxman. So does that mean I should just order a .01uf 630volt capacitor or do they actually make that same type of capacitor with a +10% something or other?

yes .01 630 volt will be fine ,ignore the 10 percent

10% something or other....

When a value is given as in your case 10% that means the value of the capacitor can vary as much a 10% one way or the other. They were not built as precesion components and the value could vary + or - 10%. I hope this help you understand. This is my understanding anyway.

Hi Scott.
When ordering, why not order 5 or 10 more to keep on hand for your next project? Buying a few extra of each value, you will soon have a small stock of caps on hand, saves time/shipping in ordering for each set you do.
Good lcuk on your project.

10% doesn't apply to the voltage. Just capacitance.

Here are a few more references to pick through.
