Types of capacitors and how they are made

Aluminum electrolytic capacitors are famous for their low cost and ability to hold large amounts of energy in a small package compared to ceramic or film capacitors. While electrolytic capacitors are very popular, they are more sensitive to unwanted voltages and temperature than other capacitors and have relatively high current leakage.
