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.
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.
Some capacitors use letter codes to indicate specific characteristics, such as tolerance, voltage rating, or the type of dielectric material used. These letter codes are often combined with numbers to give full specifications. Voltage Rating: Some capacitors mark the voltage rating using a letter code like V or WV (working voltage).
