Capacitors often have markings indicating their temperature coefficients, which show how capacitance changes with temperature. These codes are used for applications requiring consistent performance despite temperature fluctuations, such as precision electronic circuits.
In plastic type capacitors this temperature value is not more than +700C. The capacitance value of a capacitor may change, if air or the surrounding temperature of a capacitor is too cool or too hot. These changes in temperature will cause to affect the actual circuit operation and also damage the other components in that circuit.
This capacitor marking code uses three characters. It bears many similarities to the numeric code system adopted for some surface mount resistors. The first two figures refer to the significant figures of the capacitor value, and the third one acts as a multiplier.
[/su_table] (iii) Temperature coefficient codes: On several capacitors marking or code indicates the temperature coefficient of the capacitor. All these codes are standardized by EIA (Electronics Industries Alliance), these codes are typically used for ceramic and film type capacitors.
An example of the marking which can be typically observed in a capacitor is “22µF 50V”. Here, 22µF is the value of the capacitor while 50V denotes the working voltage. The marking of a bar is used to denote the polarity of the capacitor indicating the negative terminal.
Markings of Ceramic Capacitor: The markings on a ceramic capacitor are more concise in nature since it is smaller in size as compared to electrolytic capacitors. Thus, for such concise markings many different types of schemes or solutions are adopted. The value of the capacitor is indicated in “Picofarads”.
The capacitors which are small in size does not provide space required for clear markings and only few figures can be accommodated in the given space in order to mark it and provide a code for their various parameters. Thus, abbreviated markings are used in such cases wherein three characters are used to mark the code of the capacitor.
Capacitors often have markings indicating their temperature coefficients, which show how capacitance changes with temperature. These codes are used for applications requiring consistent performance despite temperature fluctuations, such as precision electronic circuits.
In addition to the above examples, capacitors may also display other specs such as working temperature range, date of manufacture, and even the manufacturer''s name. Capacitors may also indicate their tolerance with a letter placed after the first three numbers. These letters range from A (±0.05pF) to Z (-20 to 80%). The table below gives ...

Method of Finding the value/Meaning of codes of capacitor • Ceramic disc capacitors have two to three digits code printed on them. • The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. • When the first two numbers are multiplied with the multiplier, the resulting value is the value of the capacitor in picofarads.

Color codes for non-polarized mica molded and polyester capacitors like ceramic and disc capacitors are an old school method (BS-EN 60062) and hence replaced by the capacitor marking ( BS-1852 Standard) with alphanumeric codes. If you still find the old age color coded capacitor, you may identify the value of the ceramic capacitor using the following example (see fig 3(c) …

A capacitor code is a system of markings used to indicate the capacitance value, tolerance, and sometimes voltage rating of a capacitor. These codes are often used on small capacitors where there isn''t enough space to print the full value.
For example, a marking of "473" indicates a capacitance value of 47,000 pF, which is equivalent to 0.047 μF. Tolerance Rating: Film capacitors come with a tolerance rating that indicates the permissible deviation from the specified capacitance value. Common tolerance values include ±5%, ±10%, or ±20%. This information is usually denoted by a letter code …
