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.
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 read capacitor markings?
Reading capacitor markings involves identifying several key attributes. The capacitance value often marked directly in microfarads (μF), nanofarads (nF), or picofarads (pF). The voltage rating indicates the maximum voltage the capacitor can handle, marked as a number followed by "V".
What is Polarity marking on a capacitor?
The polarity marking is marked near the positive lead with a “+” sign indicating the marking. In case of a new capacitor, an additional polarity marking is placed on the capacitor to denote that the negative lead is shorter than the positive lead. The markings on the capacitors can also be done by printing it on the capacitor.
