Capacitors are characterized by their capacitance, which measures the amount of electrical charge that can be stored on the plates of the capacitor for a given voltage. The unit of capacitance is the farad (F), but in practice, capacitors are typically measured in smaller units such as microfarads (μF) or picofarads (pF).
A capacitor is made of two metal plates and an insulating material called a dielectric. Depending on the type of dielectric material and construction, various types of capacitors are available. Note that capacitors differ in size and characteristics.
Capacitors can be divided into two main types: fixed capacitors and electrolytic capacitors. Fixed capacitors have positive and negative polarities, but their capacitance value is fixed during manufacturing and cannot be changed later. Electrolytic capacitors, on the other hand, have a polarity and can be damaged if connected in reverse.
Capacitors are categorized into 2 mechanical groups. Fixed Capacitors consist of fixed capacitance value and variable capacitance with variable capacitance value. Beneath are a brief description of various capacitor types and their properties. A ceramic capacitor is considered to be one of the most commonly used capacitors.
