Customer ServiceThe nominal capacitance of a capacitor, C, is its most important characteristic. This value is measured in units like pico-Farads (pF), nano-Farads (nF), or micro-Farads (μF) and is marked onto the body of the capacitor.
This nominal capacitance value is generally measured in pico-farads (pF), nano-farads (nF) or micro-farads (uF), and this value is indicated with colors, numbers or letters on the body of a capacitor. This nominal capacitance value, which is printed on the side of a capacitor body, is not necessary to equal to its actual value.
Nominal capacitance and allowable deviation of electrolytic capacitor Nominal capacitance is the capacitance marked on the capacitor. The deviation between the actual capacitance of the capacitor and the nominal capacitance is called the error, and the accuracy within the allowable deviation range.
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.
This means the actual capacitance of the capacitor can vary by up to 20% from the marked value. So, the actual capacitance could be anywhere between 800 pF and 1200 pF. A capacitor marked with the code "473M" would be interpreted as follows:
If there is a letter following the numbers, it represents the tolerance of the capacitor, which is the range within which the actual capacitance value may deviate from the marked value. For example, a "K" indicates a tolerance of ±10%, and a "M" indicates a tolerance of ±20%.
