The Difference Between Capacitors

The tantalum capacitor is known for its high capacitance density. It is also highly reliable in many applications (so long as it is not reverse biased and is not subject to high voltages or ripple currents), although they are mostly used in decoupling, DC blocking, bypassing, filtering and timing applications.
