look at this shit.
the ripple for 1uf 50v is 71ma
what the hell can i replace that with, even rubycon YXJ is only 40ma!!!

Re: Ltec LZG
At 120 Hz it is only 0.55 factor per chart.
So the 40mA is at 120 Hz?Last edited by budm; 04-09-2016, 10:58 PM.Never stop learning

Re: Ltec LZG
no, if i'm reading right, they look worse.
it says that for 120Hz i apply a multiplier of 0.35Comment

Re: Ltec LZG
I know how you feel. I have a bunch of 5mm x 11mm LZGs and LZPs, 5 in total, that I have been trying to find replacements for over the last 3 days.Comment

Re: Ltec LZG
Size may not fit, but film capacitors like Wima MKS02 and MKS2XL will handily exceed the specs and durability of any electrolytic of value 1uF/50V.Comment

When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.
Judging from above ESR Meter Table,I think It is necessary to replace this sms capacitor.So I visited local electronics shop,and I purchased 160v 2.2uf rubycon YK capacitor.
But when I browse through rubycon YK datasheet,I found that there is no ripple current rating for 160v 2.2uf specification. But On the contrary, I found 39 mA ripple current rating for 160v 2.2uf SMS capacitor.

I have here a HP pavilion hp 15-cs2975nd with a 1.095v power supply that is driven by a FDMF3035. I do see about 80mV of ripple on my scope. I searched through the datasheet to find possible values of the ripple but I don't understand the datasheet well enough.
So I have two questions:
1) what is the typical ripple voltages of gpu/cpu on a laptop or pc mobo?
2) what would be the max ripple of a FDMF3035 that drives an output of 1.095V?
Would be nice to have a rule of thumb of say a percentage of the supply voltage to be an acceptable ripple voltage....12-09-2022, 06:51 AM -
Hi all
I need to replace a 680uF 35V SamYoung NXB cap which has got a ripple of 1820. Whilst passing my local little electronics shop I picked up what they had in stock which was a 680uF 35V Panasonic FC with a ripple of 1655.
As the ripple rating is only 9% below what the original was I am wondering whether to risk it and fit it.
The catalogues specify a capacitance tolerance of +/-20% but state nothing about the ripple. If there is a similar tolerance for ripple then I might be worrying about nothing. Does anybody know?

Hi
I have a Lenovo 530 14ikb i5 8th gen motherboard and it fails to start Windows: it normally dies after I try to load Windows. Getting into bios screen works fine.
Made some measurements and I suspect that there is to much ripple on the 2 Vcore coils.
What is normally the maximum ripple allowed on say any of the power supplies? A few %??
The ripple is on both Vcore as outlined in red in attached photos.
Could be a bad driver?

Hi fellow troubleshooters. This is my first post on badcaps. I've recently setup an electronics workbench. i'm also building a studio with old equipment bought faulty at low cost.
I've been into electronics since the mid 80's and particularly in the last few years though only getting hands on with repairs now. My knowledge gaps are significant so I'll be posting here to seek guidance advice and general practical applied learning.
On my bench today is an old ca. 1993-95 Akai hardware sampler. This runs on both a linear and Smps supply. Both are getting on in age and ripple...
