This article is here to guide you through the diverse world of capacitors. We’ll delve into twelve different types of capacitors, explaining how each works, where they’re used, and their advantages and disadvantages. By the end, you’ll have a comprehensive understanding of choosing the right capacitor for any equipment. 2.
Capacitors have several key specifications that define their performance and suitability for various applications. Some of the most important capacitor specifications are mentioned below : Capacitance is the fundamental property of a capacitor and is measured in Farads (F).
Some types of capacitors, like electrolytic and film capacitors, are bulkier than others, like ceramic capacitors. Tip: Evaluate the available space on your PCB or within your device enclosure before selecting a capacitor. 4.
Basic capacitors, formerly known as condensers, consist of two parallel plates - one positive and one negative - separated by a dielectric (nonconducting) material. The plates may be square, rectangular, cylindrical, or spherical, resulting in several possible designs and form factors.
Fixed capacitors are widely used due to their consistent capacitance value which remains unchanged when manufactured. This stability makes them ideal for applications requiring precise capacitance over time. Capacitance values for fixed capacitors can range from picofarads to frads, depending on the specific type and application.
When selecting a capacitor, it is important to consider the dielectric material used. Various dielectric material groups feature different characteristics, advantages, and disadvantages. Though it is not mentioned in this table, air is sometimes used as a dielectric in high voltage applications. Dielectric characteristics.
