Exchange of capacitors

Question

I have a question about a capacitor. Used in my monitor.
Here is my “Broken” capacitor:

And here is my “New” capacitor:

With the same parameters, but they both have a different — I don't know how it's proper call, but I think it's a name of them.

Anyway, old “Broken” has number W6A7, but new has E232.

Do those numbers have a sense? Or I can just put “new” and do not be afraid of my monitor?

Thanks in advance!

Answer 1

Does those numbers have a sense?Or i can just put "new" and do not afraid for my monitor?

Those numbers are probably just specific to the manufacturer. The important numbers for performance are: -

• 100 uF
• 450 volts
• 105 degC
• Rated ripple current at the typical circuit operating frequency
• Lifetime

The ripple current may not be shown on the device but the three values listed prior to ripple should be. However, you can't assume that because the rated ripple current isn't shown, that your replacement will be effective in your circuit or reliable.

Sometimes the lifetime rating is shown - this is the number of hours that the capacitor is judged to be able to work for without serious performance deterioration at the temperature value on full voltage and ripple current. So, when making comparisons, you should always check that the potential replacement is going to last as long (or longer) that the original device.
