Hi guys

I have this Suntac SUH286 motherboard with a busted tantalum cap next to the oscillator and for the death of me cannot identify what are the specs of that. It just has '10k' on it and as you might have noticed, I am a noob without the right tools to measure capacitance.

Any help is greatly appreciated. Thanks

It´s not a tantalum but a ceramic capacitor with 10.000pF = 10nF.
Voltage should be 50V (or higher).

I wonder what 10nF 50V could do around the crystal, being put so symmetrically. It's not the load caps, too high value

Thanks for pointing that out - I was a little hasty this morning.
10K is 10pF and K is the tolerance +/- 10%!
