Every capacitor has a special marking printed on its body. It represents the value or colour code of capacitor. There are different types of capacitor and each has its specified capacitance value, voltage rating, temperature range, tolerance and life time. But most of the capacitors have their value and their voltage printed on their body.
Colour code: Some older capacitors use a form of colour code. This type of capacitor marking is used less these days but may be seen on some older capacitors. Tolerance codes: Some capacitors have a tolerance code. The code used is actually the same as that used with resistors as it utilises the EIA scheme:
The markings on the capacitors can also be done by printing it on the capacitor. This is true for capacitors which provide enough space for marking to be printed and include film capacitors, disc ceramics, and electrolytic capacitors.
A: Capacitor code values are used to represent the capacitance value of a capacitor component. Capacitors are electronic components that store and release electrical energy. The code values help in identifying the capacitance value of a capacitor without having to write the full value in Farads. Q: How are capacitor code values expressed?
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.
• Ceramic Capacitor Markings Ceramic capacitors, known for their small size, use concise markings with digits and letters to indicate capacitance values. These codes convey information in minimal space, often including a base capacitance value followed by a letter for tolerance or temperature coefficient.
