Hello,

Have a GOOD look at the pages.
At newark you will need to buy at least 600 capacitors.
At Digikey, you can buy one if you need.

What is the application? You have to buy the type of cap that fits your usage. It says "general purpose" which means it won't work for high frequency switcher applications.

Thanks bountyhunter;tv power sup V. H. output,the thing is that i changed the 2 MCZ3001 driver ics and the tv is working great,but it was suggested by the supplyer to change the 2 big electrolitic 1200uf 250v 105degrees Rabycon,i ordered panasonic HC but they are a little larger and lower on hight don't fit there,but i also checked the ESR and Capacitance on the old caps and they measure better than the new ones i bouhgt.
my question is if they test good why should i change them?
they also suggest to change 2 mylar 0.1uf coupling caps and 2 metalized film 47 and 49 these also check good.

 

my question is if they test good why should i change them?

Age. Aluminum electrolytic caps are one of the few parts that have a predictable failure time.

Here are pics after the change of mcz3001

Which is typically a few thousand hours.

The old caps are probably higher frequency (Low ESR) types which the new Panasonics are not.

I looked at the picture, that looks like a HF switcher. Those caps had better be switcher caps with low ESR or they will not work right and will die soon.
