Difference between 16v and 16vdc caps

[gwozdz]

I am in the process of replacing the caps on my motherboard. All of the caps read like 22uf 16v. Do I have v or vdc on my computer? Does this mean I should replace these caps with those showing 16v also. What about the 16vdc caps would those work. I'm confused about this voltage thing. Thanks in advance

its dc
ac caps would read like more than 100v

My friend has some caps to give me and all of his say 2200uf, 6.3v and 1000uf, 6.3v and 220uf, 16v . So all of them end in the voltage part with just a "v", like the caps on the motherboard right now. Can my friends caps be used provided the temp range, etc is the same?

Re: Difference between 16v and 16vdc caps

yes but you must check that the capacitors are low esr
the first thing to check is that they are 105oC and not 85oC
then you check the brand / series
if you tell me that i will tell you

I don't know about the low esr status of the caps and I have no way to find it out, but if they aren't what impact would it have on using it in the motherboard. Like would it damage something or just not last as long?

no damage, just instability

what you can do is get the caps and then look at what is written on them and we can tell you if they are good or not

Re: Difference between 16v and 16vdc caps

V = volts
DC = DC (direct current)

The "V" you see assumes DC.

In other words 16 v and 16 vdc are exactly the same thing.

I don't know about the low esr status of the caps

Look it up in data sheet.

Depends.
Anything from just being unstable to exploding parts or catching on fire is possible.

I just received this info on two of the caps he has. Both are 105deg
This is what is written on each cap:

Sanyo, S.E.24, WG, 1000uf, 6.3v
Rubycon, T0229, MBZ, 3300uf, 6.3v

Does this translate into low esr or not

Re: Difference between 16v and 16vdc caps

Sanyo, S.E.24, WG, 1000uf, 6.3v
This is Sanyo WG series.
Ripple 1140, ESR .030

Rubycon, T0229, MBZ, 3300uf, 6.3v
This is Rubycon MBZ series.
Ripple 2800, ESR .012

Those are both premium brands and premium grade. [Very low ESR, high Ripple.]
- They rarely fail unless you have a bad power supply or a heat problem.

Hey Guys, Thanks for all the help. When I get the caps, then the fun starts. I need to first read more from this wonderful web site and forum. This will be my first attempt to revive a motherboard. If a set of new caps doesn't work, in the trash it goes. That's about as far as I dare to go in repairing the thing. John

If yo have Sanyo and Rubycon going bad I'd be looking at the power supply as the problem.
