audio circuit. lets say hypothetically i needed a 390pf ceramic cap and i only had a 330p and a 60p ceramic cap . can i parallel these without issue?
-
Sure, why not, as long as your max voltage is less than the smaller rating of each of the two caps.

Yes, you can parallel two capacitors to get the desired capacitance. The total capacitance will be the sum of the individual capacitances. In your case, the total capacitance will be 330pF + 60pF = 390pF which is what you need. You can use these two capacitors without any issue. However, it’s important to note that when you parallel capacitors with different values, their effective series resistance (ESR) and effective series inductance (ESL) will also be different. This can affect the performance of your circuit

I don't know if the accuracy of Bing Sidebar AI is better ....

playing around with caps in the pico range can be problematic, like all caps, they are heat sensitive, pico's are extra sensitive, wants/needs heat sinks.
they also don't like long leads. at audio frequencies it might not be a big deal. with long legs and in ||, they make "stray" capacitance between the legs :icon_biggrin:

ok so y'all know that a 390pf is a klon cap. we'll see what happens

Well, it's not the Magical Diode, so everything should be just fine.

You guys should check out the "Gartner Hype Cycle."
I don't think we've hit the "Trough of Disillusionment" on AI yet. :icon_biggrin:

like all fake stuff before, Artificial sweeteners, artificial colors..... :icon_biggrin:
what's the coding saying "garbage in - garbage out" the folly of man has no limits :laugh:

Does anyone make 200PF caps? 2 of them in parallel would get you very close to the 390PF that you want and they would be balanced. I suppose a 150PF and a 250PF would work also...
-
i have a couple of out of spec ceramics that add up to exactly 390pf parrallel'd. going with those

Right now, there are 13 radial leaded 200pF caps in stock at Mouser. I personally like Vishay and Kemet.
