The various parameters of the capacitors such as their voltage and tolerance along with their values is represented by different types of markings and codes. Some of these markings and codes include capacitor polarity marking; capacity colour code; and ceramic capacitor code respectively.
Numerical Markings One of the most common formats for capacitor markings is the numerical code. This is typically a series of three or four digits, which represent the capacitance value and sometimes the tolerance. Three-digit code: The first two digits represent the significant figures, and the third digit indicates the number of zeros to add.
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.
Thus, for such concise markings many different types of schemes or solutions are adopted. The value of the capacitor is indicated in “Picofarads”. Some of the marking figures which can be observed are 10n which denotes that the capacitor is of 10nF. In a similar way, 0.51nF is indicated by the marking n51.
Markings on the PCB: Positive Marking: Often represented by a “+” symbol, indicating where the positive terminal of the capacitor should be placed. Negative Marking: Typically denoted with a “-“ symbol or sometimes a black stripe. The negative terminal of the capacitor should align with this marking.
While most modern capacitors use numerical markings, older models often display color codes. These codes indicate values like capacitance and breakdown voltage through a series of colored bands. Figure 2: Standard Capacitor Color Code Each color band on a capacitor represents a specific number or multiplier.
