Re: Need to get specs for this electrolytic cap please
Thats great! Many thanks for your help redwire!
I couldn't find the ESR value in the specs so I calculated it from the given Tanδ value, which came to be 1.59 Ω. That calculation is done at 120Hz however that cap is working as an input filter for dc-dc converter running at 1Mhz so its ESR would be much less...
I guess it would be okay to replace it with a new cap of a much lower ESR value?
thanks againLeave a comment:

Need to get specs for this electrolytic cap please
Hi,
I would be very grateful if the make of this 100uf 35V smd cap in the photo can be identified. It is used in dc-dc converter on a 15 years instrument board that is fairly used. I would ideally like to find its specs in order to replace it with a similar one, that has similar ripple current, ESR, etc.
Thank you!... -

Re: Need to identify these caps please
Thank you R_J. Are these ones tantalums too.
Are they 100uf 10V?
what are the other markings on them?

Hi,
I Would be very grateful if the type of the 10uf 25v caps in the photo can be identified, these are on a 15 years instrument board that is fairly used.
Are these solid electrolytics?
Would these go bad?
Thank you!... -
