Re: capacitor ripple vs endurance & other questions



I'm located in winter springs, FL



I've tried searching these places for the brands, but the only place that had the type and size that I needed was mouser (found nichicon hv, but they have none in stock & the lead time is 19 weeks). Guess I'll have to settle for a lower grade capacitor......

Re: capacitor ripple vs endurance & other questions

I managed to find capacitors for all the other values except for the 470uf @ 25V (10x16mm).

I want to use either Nic Components NRSJ, NRSK, sanyo WG, or Rubycon ZLG, but I'm having a hard time finding someone who sells these capacitors. Does anyone know of any good suppliers that carry one of these brands in the specified size above?

Re: capacitor ripple vs endurance & other questions



Yeah same here, the information everyone has placed here has helped me alot. I finally understand what all of the values are and what they do now. Thanks guys!...

Re: capacitor ripple vs endurance & other questions

I see, so endurance is practically useless, thanks for clearing that up for me.


here's a list of the old capacitors that I plan to replace:

brand -------- specs

elite PF ------ 1000uf @ 16V ( 10 x 20 mm)
capxon KF --- 1000uf @ 10V ( 10 x 16 mm)
capxon KF --- 470uf @ 10V ( 8 x 11.5 mm)
capxon KF --- 470uf @ 25V ( 10 x 16 mm)
skywell SHT - 1000uf @ 6.3V ( 10 x 12 mm (not sure about height since I could'nt find datasheet for SHT) )
Sacon FZ ---- 330uf...

Re: capacitor ripple vs endurance & other questions

I apologize, here are the values of the capacitors that I need and the sizes as well:

330 uf @ 16 V ----------- 8 x 12 mm
1000 uf @ 6.3 V ---------- 10 x 12 mm
1000 uf @ 10 V ---------- 10 x 16 mm
470 uf @ 25 V ---------- 10 x 16 mm
470 uf @ 10 V ----------- 8 x 11.5 mm
1000 uf @ 16 V ------------ 10 x 20 mm

Re: capacitor ripple vs endurance & other questions

Hey thanks for replying!

So even though endurance is not tested in a typical operating condition, wouldn't a capacitor rated at 4000 hours @ 105C be better than a capacitor rated at 2000 hours @ 105C? I've been repairing a few monitors & video cards lately using capacitors that I picked up at a local electronics store, but I want to start using the most reliable capacitors possible for my repairs (I was planning to buy some of the mcz and mbz rubycons from here, but rubycon doesn't make that line in the capacitance...

Hello, I have a few questions regarding some of the specifications found on capacitor datasheets.

1.) Which specification of capacitors is more important, endurance or rated ripple? Nichicon HE capacitors have a higher endurance rating than HZ, so wouldn't they be better?

2.) Not all data sheets list esr, so how can I tell what capacitor would be better than another one?

3.) Nichicon HZ capacitors have a higher ripple rating than Rubycon MCZ capacitors, so would the nichicon HZ be better than the Rubycon in this case?

4.) Also, what...
