6 FAQs about [Capacitor identification and standards]

What are the different types of capacitor markings & codes?

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.

How to identify a 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.

Why do capacitors have abbreviated markings?

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.

What are the different types of coding system used for capacitors?

The different types of coding system used for the capacitors are: Colour Code: A “colour code” is used in capacitors which are old. In the present times, industry rarely use colour code system except seldom on some of the components. Tolerance Codes: The tolerance code is used in some of the capacitors.

What does a color code on a capacitor mean?

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.

Why do capacitors use tolerance codes?

Capacitors use tolerance codes, much like resistors, standardized by the Electronic Industry Alliance (EIA). These codes indicate how much the actual capacitance may deviate from the marked value. This precision is ideal for designing and maintaining high-accuracy circuits.
