Tantalum Capacitor vs Ceramic - Sensible Micro

Tantalum capacitors are typically polarized. This means that they can only be connected to a DC energy supply observing the correct terminal polarity. Ceramic capacitors, on the other hand, are non-polarized and can be safely connected to an AC source. By not being polarized, ceramic capacitors have a better frequency response.
