Many of these specs are different ways of expressing the same thing. Q and ESR (equivalent series resistance) both express the loss in the capacitor. $$ Q = {\left| 1 / (2 \pi f C)\right| \over \text{ESR}}$$ Strictly speaking ESR can change with frequency due to things like skin effect, but this equation can get you close enough to make a comparison as long ...

I bet you can make this work reliably with an SMT MLCC. You just need something bigger than an 0603. If you switch to leaded capacitors you're going to have a much harder time finding high frequency data since the lead inductance starts to become significant at hundreds of MHz. I'd suggest searching with manufacturer tools rather than distributor tools. You'...
