We have some MLCC capacitors that show some discoloration, or spots. Does anyone know if this will affect reliability? Caps test good - and assemblies function perfectly.

have not seen this issue personally, often identify cracks on MLCC parts but never dark spots. May be worthwhile to replace as a precaution if at all possible.
