Simple cap question.

[Dang]

Can I replace a 2700uf electrolytic cap @16v with 4700uf cap @16v? having trouble sourcing locally, thanks.

Re: Simple cap question.

Not really its too big a gap - you can usually go 1 step higher so 3300.

cpc have them but you have to buy 5

Yep, I've tried locally but no go, just 4700uf, looks like Ebay it is, thanks by the way.

Re: Simple cap question.

You can solder a 2200uf and a 680uf in series and get 2880uf or any combination of caps to make the uf value you need in a pinch.Try to use caps of about the same size. Don't worry if the voltage value goes up, that's ok. I do that sometimes just to see if the tv works. I always put the right cap in when it arrives in the mail. Just a thought. Good Luck

I wouldn't buy caps from ebay, Selldoor has it right, try CPC

I believe that is actually incorrect you would need to have the 2 smaller value caps in parallel - not like resistors

This is absolutely correct.

I am so sorry I did mean parallel not series. I was getting my 5 y/o grandson ready for school. I must think before I type.

Re: Simple cap question.

Selldoor, is right, buy through his source, but depending on the circuit, paralleling to to high a cap value can strain the circuit feeding it. Splitecretes parallel would work OK, and JJR is right as well, don't buy caps from E-bay!

Re: Simple cap question.

What is Splitecretes parallel? I'm unfamiliar with that term.

"You can solder a 2200uf and a 680uf" (he said series, but meant parallel)

Oh, I'm sorry. It's the guy's name. Doi!

I bought Nichicon from eBay, actually was sent Nihoncon...!! Do not buy capacitors from eBay unless there is no other option!

Re: Simple cap question.

One thing to be aware of is. If the capacitor is used in timing , it can trow off the frequency that iit was deigned to operate at and cause other issues. Example is cap in 5vdc standby circuits. This is usually a ESR or Capaciitance value change issue causing the circuitry not to work

Re: Simple cap question.

So I changed the offending 2700uf cap for a 2200uf and 1000uf in parallel, Tv is now working perfectly, been on for over 6 hours without fault so thanks for all the help and advice, it's much appreciated.
