Capacitor Marking
A capacitor marking is a code, which indicates the value of the component. It usually consists of three numbers, which indicates the value, and a letter, which indicates the tolerance. Tables usually provide a means to decode the numbers; however, there are also calculators available as well. It is easy to decode because the first two numerals

Capacitor Guide, your guide to the world of capacitors
This is the main parameter to describe a capacitor. The capacitance is the largest when the distance between the conductors is small and the surface of the conductors large. Ideal capacitors are described solely with capacitance, but in the real world some limitations exist. For example, the conductors and lead wires cause parasitic inductance

6 FAQs about [Capacitor parameter marking rules]
How do you mark a capacitor?
The two types of general marking systems followed for marking the capacitors are: Markings which are non-coded: one of the most common processes adopted to mark the parameters of a capacitor is to create a marking on the case of the capacitor or encapsulating them in some manner.
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.
What is a capacitor marking?
Capacitor markings are used for identifying their values and proper usage in electronic circuits. Here's a detailed breakdown of the key aspects to consider: On smaller capacitors, you often find only the capacitance value. For larger capacitors, two main parameters are displayed: capacitance and breakdown voltage.
Why are capacitors marked with a code?
Capacitors are often marked with codes to show the value, tolerance and material. This is particularly true for small types such as ceramic disc or polystyrene where there is little space for full markings. The capacitance value is often marked using a 3 digit code.
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.
How do you know if a capacitor is safe?
Voltage Rating: Some capacitors mark the voltage rating using a letter code like V or WV (working voltage). For example, a capacitor with a marking of 25V indicates that the capacitor can safely operate at 25 volts. Tolerance: Tolerance is typically marked with a letter following the capacitance value. For example: J means ±5% tolerance.
