Understanding Capacitor Types and Characteristics | DigiKey
The principal advantages of the electrolytic capacitor are high capacitance values, small size, and relatively low cost. The capacitance values have a wide tolerance range and relatively high leakage currents. The most common applications for electrolytic capacitors are as filter capacitors in both linear and switching power supplies (Figure 5).

A supercapacitor is a specially designed capacitor which has a very large capacitance. Supercapacitors combine the properties of capacitors and batteries into one device. Characteristics Charge time Supercapacitors have charge and discharge times
Figure 8.2.5 : A variable capacitor. For large capacitors, the capacitance value and voltage rating are usually printed directly on the case. Some capacitors use "MFD" which stands for "microfarads". While a capacitor color code exists, rather like the resistor color code, it has generally fallen out of favor.
