Are these caps any good?

[MorTus]

I've been looking around for good quality caps and ones that are the correct ratings. I think i've found some, could someone in the know check that i've got it right?

from www.farnell.com goto the australian version of the site.

then look up the numbers

Cat no. 769071 = 1500uF 10V 10mmx23mm
Cat no. 768406 = 1000uF 10V 8mmx20mm
Cat no. 769150 = 1000uF 16V 10mmx20mm

They should be Rubycon Caps with 105 degrees temp rating and ultra low impedance.

Are these good caps? These should be direct replacements for my VP6.

N.B. Sorry about not posting direct links, the website is really nasty.

Rubycon ZL series. They are used in many motherboards. Also YXG series is used. Should be excellent.

The Rubycon MBZ series are also one of the best and lowest ESR available.

Features of MBZ Series
Capacity as high as 1.5 times the ZL Series
50% lower impedance and ESR than the ZL Series
Ripple current as high as 1.3 to 1.5 times the ZL Series
Use : CPU power supply on motherboards
Service Life : 2,000 hours at 105degC

MCZ series
105ºC, Ultra Low ESR
MCZ series has achieved lower ESR at high frequency from conventional MBZ series by approximately 40%. The series is recommended for VRM for higher speed CPU's.

interesting. both have shorter life though. 2,000hrs when ZLH (New ZL) and YXH (New YXG) have 5,000 - 10,000 hrs. does the difference really matter for our purposes?

Generally the larger diameter electrolytic caps have longer service lives. I've got a bunch of Nichicon UPW series caps, which can be "interesting" to fit on a motherboard, especially the 3300's, but i think they're rated for 7K hours.

service life

I think that service life does matter. 2000 hours is less than 3 months of continuous running time.

cap life is measured at 105degC, actual life is longer at lower temperatures like double every 10degC lower.
