Hey guys, Starting a new project here and i dont have correct value cap i need 33pf but i have 10 pf and 22pf was wondering if it was possible to combine 2 caps to get the correct value?
Thanks for the reply time to get to building!Sure, you can combine them in parallel and the total capacitance will be the cumulative total. Buying the proper capacitor value is more ideal but yes, you can do this in a pinch.
Don't just take my word for it, here's more information on combining capacitors (for reference): https://learn.sparkfun.com/tutorials/capacitors/capacitors-in-seriesparallelThanks for the reply time to get to building!
This just made me even more confident knowing this isnt as rare as i thoughtDon't just take my word for it, here's more information on combining capacitors (for reference): https://learn.sparkfun.com/tutorials/capacitors/capacitors-in-seriesparallel
Downloading ASAP!I have a free groovy little app called EEToolkit. It does and SHOWS a lot of the math, obviously this one is easy enough to calculate, but it quickly answers the question of “what happens if I?”

Yeah, I just realized I upgraded too!I loved it so much I got the pro version. I’ve been using it since it came out. Super helpful.
i have ios its on there id imagine android too?Is that available on android or just IOS? I can't find it on the Google play store.

thank you for the info! knowing this going forward is going to make these builds much easier without having to spend more moneyYep, as you already know by now. I do parallel cap footprints in certain critical locations on my own designs. So if I need a 1.12uF coupling cap to get the right bass rolloff it's no problem. This is really useful for resonant filters too.
Not just being chained to stock ISO values can be quite liberating. Even some of the stock values like .82uF can be very hard to find and out of spec/counterfeit parts end up coming into play fairly often.thank you for the info! knowing this going forward is going to make these builds much easier without having to spend more money

Yep, but don't forget that you can put passive components in series to get new values as well. Doing the math ourselves in never a bad idea IMO, but an app like @fig linked or LTspice modeling makes this stuff trivially easy these days.This golden info for me i love learning ways around things. Exactly as you said its very liberating knowing i dont have to constrained anymore by *inbetween* values. So this is probably obvious but i should ask anyways this will work with resistors as well just use the teepee method?
I need to start messing with LTspice i have it downloaded but havent really played with it yet.Yep, but don't forget that you can put passive components in series to get new values as well.

It's a fantastic tool that I use nearly every day. You can download things like whole Fender tube amp models to get started: https://groups.io/g/LTspiceI need to start messing with LTspice i have it downloaded but havent really played with it yet.
