Hi Peeps,
Trying to resuscitate a half-dead motherboard (not booting or beeping, power switch works and CPU fan spins , but thankfully not destroying CPUs or RAM)
A couple of the caps are slightly non-flat, and i have read they they are prone to fail.
There is 7 of these on the motherboard, and they are all the same specs
Here is the Original capacitor specs
Brand :OST
Series : RLX
Capacitance : 2200uf
Voltage: 6.3v
MAX Op Temp : 105 deg Celsius
Dimensions 10mm X 20mm
There is another number written on the caps : 0338 - what is this? (is it 0.0338 impedance?)
I looked up the datasheet for the OST RLX series and they state that ripple is 2500 mArms and impedance is 0.015, for this particular capacitor.
The best that i can find is here:
http://au.rs-online.com/web/p/alumin...itors/5260982/
It is a panasonic, that closely matches the original
(the OST capacitor's impedance of 0.015 is out of the range of this panasonic's, which is 0.018 - 0.054
I'm picking that a lower impedance is not ok?
Also have read that it is best to get a cap with the same, or higher, ripple current rating that the original.
This panasonic is the one with the highest ripple current rating (2470mArms) - just short of the original 2500mArms
Have i chosen the best one from au.rs-online.com,
or should i look for a one with a higher ripple current rating, higher impedance (and a bit higher capacitance, because there is no 2200uf's that are suitable)?
Thanks
