What are the characteristics of electrolytic capacitors？

First of all, we need to understand the characteristics of electrolytic capacitor, before we know why the main board, graphics card, and almost all computer equipment used in electrolytic capacitors:

Electrolytic capacitors feature 1: the capacitance per unit volume is very large, tens to hundreds of times larger than other types of capacitors.

Electrolytic capacitor feature 2: rated capacity can be very large, can easily achieve tens of thousands of μ f or even a few f (but can not be compared with the double layer capacitor).

Electrolytic capacitors feature 3: the price has an overwhelming advantage over other types of electrolytic capacitors because the components of electrolytic capacitors are common industrial materials such as aluminum and so on. Electrolytic capacitor manufacturing equipment is also ordinary industrial equipment, can be large-scale production, relatively low cost.
