For large capacitors, the capacitance value and voltage rating are usually printed directly on the case. Some capacitors use "MFD" which stands for "microfarads". While a capacitor color code exists, rather like the resistor color code, it has generally fallen out of favor. For smaller capacitors a numeric code is used that echoes the color code. Typically it consists of a three digit
A capacitor is a device used to store charge, which depends on two major factors—the voltage applied and the capacitor’s physical characteristics. The capacitance of a parallel plate
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.
The property of a capacitor to store charge on its plates in the form of an electrostatic field is called the Capacitance of the capacitor. Not only that, but capacitance is also the property of a capacitor which resists the change of voltage across it.
Capacitors are said to have good voltage characteristics when this variance width is small, or poor temperature characteristics when the variance width is large. When using capacitors in electronic equipment used for applications such as ripple rejection in power lines, the design must take into account the operating voltage conditions. 1.
When it comes to importance, the nominal value of the Capacitance, C of a capacitor will always rank at the top of capacitor characteristics. This value can be measured in three ways: These values are printed directly onto the body of the capacitor in letters, numbers, and colored bands.
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.
The value of nominal capacitance is specified on the body of the capacitor either as numbers or letters or color bands. The nominal capacitance of a capacitor can change with a change in the supply frequency and the operating temperature. For a small-sized ceramic capacitor, the nominal capacitance can be of the order of one pico-Farad, (1 pF ).
