The Ultimate Capacitors Guide: Learn How To Use Them
Aluminum capacitors are part of the electrolytic family. These capacitors use aluminum oxide as the dielectric. This type is very common and fairly cheap. They perform well in low frequency applications, so you often see them in DC power supply filtering and audio circuits. They are polarized, so you have to be careful how you hook them up.

Filter Capacitor
How filter capacitors work is based on the principle of capacitive reactance.
