This 18,000 µF electrolytic capacitor is well-suited for
applications requiring substantial energy storage, like filtering DC power
supplies, smoothing ripple currents, and providing a reserve of charge for
power-hungry circuits, especially those operating with DC or pulsating DC
voltage.
They are also used to great affect when generating “sound”
in the audio equipment field.
In fact, these capacitors in a unit of audio equipment have
significant impact on the quality of sound.
