ceramic capacitor

[Vrystaat]

Gooday all,
Can anybody please tell me if you can use a multilayer ceramic cap in the place of an ordinary ceramic cap ? The values are the same.

Yes!

Thanks Osvaldo !

depends on the specs required. for general supply bypassing, yes. if temperature stability or accuracy are important then spec comparison is in order.

The only good ceramic capacitor are the NPO (COG) best use any metalic film, at least poliester. You can read about capacitors in this web page, perhaps the best work about capacitors ever made:

Capacitor Sounds, Speaker Cables and Crossover Inductors.

Thanks for the great info you all !

Yea, stay away from X7R and Z5U in audio.

NP0´s are needed only in VFO´s and anywhere can be frequency drift with temperature,in audio, a +-20% temperature derivation is of no care.

It's not the tempco of class 2 and 3 ceramics that are the problem. The capacitance varies with voltage which is a direct cause of 3rd order IM distortion. NPOs are needed anywhere you need to keep the signal clean. For a rail bypass cap, you might get away with a class 2 or 3. For a Miller cap, phase lead comp, coupling, or a tone control - don't.

Oh, a big thing to make an audio oscillator using them as giant varicaps!
