A capacitor consists of two metal plates and an insulating material known as a dielectric. Depending on the type of dielectric material and the construction, various types of capacitors are available in the market. Note: Capacitors differ in size and characteristics.
Ceramic capacitors, especially the multilayer style (MLCC), are the most manufactured and used capacitors in electronics. MLCC is made up of alternating layers of the metal electrode and ceramic as the dielectric. And due to this type of construction, the resulting capacitor consists of many small capacitors connected in a parallel connection.
Capacitors come in many forms, each designed for specific applications and operating conditions. Let’s take a closer look at the most common types of capacitors: Ceramic capacitors are small and stable, often used in high-frequency applications such as shortwave radio and aviation air-to-ground communications.
The dielectric material between the two plates is the main element of the capacitor that gives rise to the different properties of the different types of capacitors. The type of internal dielectric, the structure of the plates and the device packaging all strongly affect the characteristics of the capacitor and its applications.
Voltage limited to about 100 V. Explodes when voltage, current, or slew rates are exceeded or under reverse voltage. Energy density typically tens to hundreds of times greater than conventional electrolytics. More comparable to batteries than to other capacitors. Large capacitance/volume ratio.
Variable capacitors are made as trimmers, that are typically adjusted only during circuit calibration, and as a device tunable during operation of the electronic instrument. The most common group is the fixed capacitors. Many are named based on the type of dielectric.

Electrolytic capacitors are known for high capacitance values, and they are essential in power supply filtering. They have polarity, requiring correct orientation in circuits, and are ideal for storing large amounts of charge. They are widely used in power supplies to smooth output and in audio applications for coupling and crossover networks.
You''ll find one or more capacitors in almost every electronic circuit you build. And capacitors come in all sorts of shapes and sizes, influenced mostly by three things: the type of material used to create the plates, the type of material used for the dielectric, and the capacitance.

Capacitors with different physical characteristics (such as shape and size of their plates) store different amounts of charge for the same applied voltage (V) across their plates. The capacitance (C) of a capacitor is defined as the ratio of the maximum charge (Q) that can be stored in a capacitor to the applied voltage (V) across its ...
Ceramic capacitors of special shapes and styles are used as the capacitors for RFI/EMI suppression, as feed-through capacitors, and in larger dimensions as power capacitors for transmitters. Based on the working temperature range, temperature drift, and tolerance, ceramic capacitors are divided into three classes:
