They are out of a Onkyo txsr875 receiver
Hello ns2_1982,
It appears that the 10000uF capacitor may be 493-1049-ND and the 2200uF may be 493-12774-1-ND.

Thank you so much I’m new to all this and its a pain trying to figure out what is what so I can hopefully order it
Hi,
I don’t know where to ask my question, but I bought a 1F 2.5v capacitor at the beginning of February on your site and I haven’t found any information on the net.
My question is to know if it is normal that the capacitor has continuity between the two contacts (+ and -) “ground”? I tested the capacitors before installing and according to an electronics repairer this is not normal. So I did not install it it is still in new condition.
The capacitor is for a first generation XBOX, clock capacitor.
thank you
One of our engineers might be better able to advise, however your meter might be struggling to charge the supercap which is why it’s looks like it’s conducting.
Does the value change slowly while you’re doing the test? If that’s the case that’s normal when doing a continuity test on a capacitor.

Good call, @Kristof_2649.
A 1 F capacitor would appear as a short circuit to most voltmeters.
Most meters use a slow AC signal (with DC offset) to charge and discharge the capacitor. Capacitance is then determined by measuring the time constants. The voltage on the large capacitor will not change.
Cordially,
Aaron
