Just a general question. Are 2 capacitors in series (e.g 2 x 10nf to produce 5nf) as stable as a single capacitor in terms of capacitance value or would it be better to use a single 4.7nf capacitor for a stable outcome?
The principal 'annoyance' attending series connection of high impedance/quasi high impedance components (e.g. capacitors) is the requirement of EMF equalization (aka 'balancing')... While obviation of said requirement may be achieved via use of components specified at or above the (total) applied EMF, such is not always practical (especially as increased operating EMF is generally the objective of such connection)...Just a general question. Are 2 capacitors in series (e.g 2 x 10nf to produce 5nf) as stable as a single capacitor in terms of capacitance value or would it be better to use a single 4.7nf capacitor for a stable outcome?

Have you tried another cap? Tweaking designs with that chip is not simple.Mmmm, that's interesting @Hypatia's Protege. I'm having an issue with higher frequencies generated by a function generator chip (XR2206) where I used two 10nf capacitors in series between two of the ic's pins to give me the 5nf I needed and wonder if a varying EMF could have something to do with the stability issue I'm experiencing when this series capacitor arrangement is hooked into circuit (there is no issue when a higher value capacitor is switched in, in parallel to this arrangement, for lower frequency production.
