    What type of capacitors have the least tolerance (precision) for low voltage (<16V) and in pF-nF range?

    Look for a dielectric called either COG or NPO. I forget what they stand for but they have good initial tolerance and the least variation over temperature.

    Hello,

    I always have used polystyrene (styroflex , styrol) capacitors for stability.
    Read more about them on this page of the "cap-site":
