I already bought the replacement caps, 22pf monolithic NPO ceramic. Is this right?

Thanks

Default Optimum Capacitor Type

As an extension of jarthel's original question - What is the best type of capacitor to use in standard 2 cap/crystal oscillator circuit.

Regards, Eric.

Based on my question regarding these in several forums, I think you must use an NPO ceramic. There's no other substitute. You may be able to use silver mica? maybe not sure.

can i used silver mica for clock caps
it is stated in the farnell catalog that the tolerance is 1% compared to the normal clock cap NPO tolerance is 5%
the values are low 10pf
should be better in terms of tolerance to replace the cap rite?

Default NPO or MICA

The Mica is a better cap for this application, however the NPO
has a bit better temperature stability @ at 125C, don't believe that an issue. The NPO's are normally tighter tolerance parts than Z5U or X7R's.
