How to measure capacitance of a capacitor?
Generally the capacitance value which is printed on the body of a capacitor is measured with the reference of temperature 250C and also the TC of a capacitor which is mentioned in the datasheet must be considered for the applications which are operated below or above this temperature.
How are capacitors rated?
Capacitors are rated according to how near to their actual values they are compared to the rated nominal capacitance with coloured bands or letters used to indicated their actual tolerance. The most common tolerance variation for capacitors is 5% or 10% but some plastic capacitors are rated as low as ±1%.
What are the characteristics of a capacitor?
A capacitor comes with a set of characteristics. All these characteristics can be found in datasheets that are provided by capacitor manufacturers. Now let us discuss some of them. One of the most important one among all capacitor characteristics is the nominal capacitance (C) of a capacitor.
What is the nominal value of a capacitor?
The nominal value of the Capacitance, C of a capacitor is the most important of all capacitor characteristics. This value measured in pico-Farads (pF), nano-Farads (nF) or micro-Farads (μF) and is marked onto the body of the capacitor as numbers, letters or coloured bands.
What is the equivalent circuit of a capacitor?
It has always been a surprise for engineers to know that the equivalent circuit of a capacitor includes an effective serial resistance (ESR) and an effective serial inductance (ESL), as shown below. The internal resistance is because of the materials, design, and manufacturing process.
What is a capacitor used for?
A capacitor is one of the basic circuit components in electrical and electronic circuits. Capacitors are used to store energy in the form of an electrostatic field. Capacitors are available in several different types and sizes. Each type of capacitor has its unique characteristics and specifications that impact its performance.

Ceramic Capacitor FAQ and Application Guide
S-Parameters or scattering parameters are used to describe how RF energy travels through a network (filter, amplifier, capacitor, etc.). As an analogy, S-Parameters can be compared to light traveling through a pair of glasses. Some light reflects off the lens toward the source, some travel through the lens to the eye, and some light is absorbed by the lens. Similarly, RF energy can …
6.1.2: Capacitance and Capacitors
Some dielectrics are notably more efficient than others.
