What is a Capacitor? Definition, Uses & Formulas
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other.
ceramic capacitors, is an unfortunate fact of nature which will be discussed more completely later. A typical question is why industry makes commercial capacitors with any-of the materials having lowvalues of K. The answer generally lies with other capacitor characteristics such as stability with respect to temperature, voltage ratings, etc.
There are many characteristics and specifications which appear on a capacitor''s datasheet which holds significant value to the nature of the capacitor. These include …

2.1 General-purpose grade and long-life grade capacitors Aluminum electrolytic capacitors are generally divided into two basic reliability categories: capaci-tors for high-reliability applications and capacitors for general-purpose applications. This differen-tiation has also been adopted in the relevant IEC standards.
