Re: Replacing oddball electrolytic - 1650uF
Should I worry about the drop from 10V to 6.3V??
6.3V 3300uF, I have no problem with... The sky's the limit with these, there are plenty of these in 10mm.Comment

Re: Replacing oddball electrolytic - 1650uF
No. - It's on either 5v or 3.3v so either works fine.Mann-Made Global Warming.

Are those big 10V caps on PSUs always either 5V or 3.3V, or are they sometimes really 10V? In other words, is it always safe to replace them with 6.3V? Forgive my ignorance.Comment

Re: Replacing oddball electrolytic - 1650uF
The standard output voltages of an ATX power supply are +12, +5, +3.3, -12v. There aren't any voltages from 6.3v to 10v so there's no need for a 10v capacitor on the output side. There could be 6v-10v on the input side or anywhere in a proprietary power supply.
If in doubt solder a cap in a measure the voltage. A 6.3v cap will run at 10v long enough to measure it.Comment

Re: Replacing oddball electrolytic - 1650uF
I just tested the 350-PN... There are six "big" caps. Two of them were 4.82V, two were 12.9, and two were 3.36, so to answer my own question, none of them were unique to the design. They each just represent a different "rail".
I'm about to re-cap this with Panasonic FK and FC. The FK has better spec than the Teapo SC, so I'm glad I listened to you and did not use the Samxon RS. Thanks.Comment

I do have several old pc motherboards which i recapped 10 year ago and some of those caps are bulged now.
I would like to upgrade them using solid capacitors. I do use them for testing and helping some alternative operating systems.
I would like to ask if such an upgrade can be done, what should i have in mind when replacing electrolytic by solid caps and if such thing exist, if there are caps list for old motherboards. I would have to figure out what caps needs each motherboard and then prepare a list to try to ask for them on some electronics stores. -
First of all, I'd like to mention that I'm a novice when it comes to laptop repair, although I do have some experience with soldering.
One day, my laptop experienced a severe stutter, and after rebooting, it failed to boot into Windows. I decided to disassemble it and found that the PL900 component was blown. Later, I came across a post (https://www.badcaps.net/forum/troubl...error%E2%80%99) with the same problem, where...08-30-2024, 06:13 AM -
Hello guys,
I need an explanation from more experienced guys regarding the replacement of faulty (bumped) caps.
I recently oversaw a replacement of faulty caps on two different motherboards. On one motherboard we have 5 faulty caps, 3 x 3300 uF and 2x 1500 uF 6.3 V. I have witnesed that all caps were replaced by 2200 uF 6.3 V and it worked ok.
Is there any recommendation about how to proceed if I don't have exact capacitors? Usually it is beeter that replacement capacitor has higher voltage and a bit higher capacity (if same is not available). Is it possible that... -
Hello,
can I use this cap:
https://www.tme.eu/en/details/ues1h4...tors/nichicon/
Capacitor: electrolytic; bipolar; THT; 47uF; 50V
to replace this capacitor: Electrolytic Radial E 47uF/50V 6.3x11 RM2.5 105°C Jamicon
What exactly I can expect to install bipolar electrolytic cap instead a regular one?
Thanks. -
From what I've found, the endurance of a liquid electrolytic cap is determined by the loss of electrolyte. If a cap is rated for 1000 hours. That's typically for a straight run test. How would the life vary if the cap is intermittently heated to its rated temperature (105C). Maybe for an hour at a time then cooled back to 30-40C (just a random number). Would the life still be 1000 hours?
Does it make a difference in the life expectancy if the cap is heating from ripple current (internal heating) instead of from the external ambient temperature?
Why do polymer capacitors...
