NPO types are ceramic capacitors, and are typically available only in small
sizes. For 0.1 uF, you should be able to find a foil type which is stable
for changes in temperature. Try a polycarbonate capacitor. (This refers to
the type of plastic dielectric used between the metal foil plates.) Admittedly,
foil capacitors in this size are large and bulky, but ceramics aren't the way
to go if you want stability.
