crivoli Posted May 23, 2006 Report Share Posted May 23, 2006 Can someone please explain the leads of this variable capacitor and how to hook it up?I have never used one and I want to make sure I get this correct.Thanks-crivoli Quote Link to comment Share on other sites More sharing options...
aProgrammer Posted May 24, 2006 Report Share Posted May 24, 2006 160 + 60 = 220if you connect O and A you get 220pF max Quote Link to comment Share on other sites More sharing options...
crivoli Posted May 25, 2006 Author Report Share Posted May 25, 2006 So is that a wire from O to A and then a wire from A to the circuit and a wire from O to the circuit, and dis-regard G all together?Sorry, I am new to this!In my mind I see a wire from A to the circuit and G to the circuit gives me 160O to the circuit and G to the circuit gives me 60A to O with a wire from A to the circuit and O to the circuit is 220.Are these correct or just plain wrong?Thanks again Quote Link to comment Share on other sites More sharing options...
audioguru Posted May 25, 2006 Report Share Posted May 25, 2006 So is that a wire from O to A and then a wire from A to the circuit and a wire from O to the circuit, and dis-regard G all together?Then you have shorted the variable capacitor with the wire.In my mind I see a wire from A to the circuit and G to the circuit gives me 160.Yes.O to the circuit and G to the circuit gives me 60.Yes.If you want their total capacitance of 220pF then connect them in parallel. Connect A to O and to the circuit and connect G to ground in the circuit. Quote Link to comment Share on other sites More sharing options...
crivoli Posted May 25, 2006 Author Report Share Posted May 25, 2006 Thanks a ton for the response.Just to double check I am thinking of this correctly:A wire goes from A to O. Then a wire from O tp the circuit. ( this is connecting them in parrell, or did you mean in series? ). Then a wire from G to the circuit. This gives me the 220pf?So I would have only two wires running from the cap to the circuit, not 3, and I would have the 220pf. Is that correct?Thanks againPS. Is there a schematic of a variable cap I can find online? Thanks Quote Link to comment Share on other sites More sharing options...
