What are capacitors? First off, capacitors store energy. Consequently, this is done by storing charges on two conductive plates, separated by a non-conductive material (aka as the dielectric). Additionally, there are different types of capacitors. Capacitors come in different shapes, sizes, and colors.
Capacitors are one of the main components in all electronic devices and are vital to their operation. In modern electronics, you will most commonly find ceramic capacitors decoupling power supplies for almost every

Polyester film capacitors are the best type of capacitors when you need high stability, and/or low source impedance. They are usually relatively expensive in comparison to other dielectric materials. Also, they have a low dielectric constant meaning their capacitance is low for its size.
A capacitor is made up of two conductive plates, which are separated by an insulating material called a dielectric. The plates are usually made out of materials like aluminium and copper, and the dielectric can be made out of materials like ceramic, plastic and paper. Capacitors can range in voltage, size and farads (F) of capacitance.
Polyester film capacitors are ideal for applications which require moderate precision, like timing circuits. Polypropylene film capacitors have great stability and low dielectric losses, making them the perfect option for high-performance applications, such as audio equipment.
As touched on earlier, polymer capacitors are excellent for high-frequency applications in comparison to their liquid electrolyte counterparts. While not as good as a ceramic capacitor, they are very close and can offer high capacitance for a similar price and board footprint when compared to the ceramic capacitor option.
Class 1: offers high stability and low losses for resonant circuit applications (NP0, P100, N33, N75, etc.). Class 2: offers high volumetric efficiency for buffer, bypass, and coupling applications (X7R, X5R, Y5V, Z5U, etc.). Class 1 ceramic capacitors offer the highest stability and lowest losses.
Ceramic capacitors are made from ceramic materials that use conductive plates as electrodes. They are the most common type of capacitors due to their versatility in use, economically low cost, and smaller in comparison to others.
