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.
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".
The unit for capacitance is microfarad, and it is denoted by the Greek sign μF. In summary, the capacitor symbols are imperative in reading electrical schematics where the capacitors are correctly installed in the circuits. Capacitors can be categorized as fixed, variable, polarized, non-polarized, and specialized capacitors.
The capacitance value on a capacitor symbol is represented by a numerical value followed by the SI unit of capacitance, which is the Farad. However, these values can be in microfarads (µF) or picofarads (pF) for capacitors with small capacitance values.
They range in size from the head of a pin to somewhere in the vicinity of a soda can, so both the characteristics of capacitors and the ability to print information on them vary greatly. The pertinent specs of a capacitor include: Polarization: Some (but not all) capacitors have a positive and negative lead.
One of the lines may be curved for polarized capacitors, such as electrolytic capacitors, or the plus "+" symbol is used on the positive side. The symbol does not depict the actual physical layout of the component. Still, it helps understand its function - storing and releasing electrical charge - and how it is connected to the circuit.

Capacitors are divided into two mechanical groups: Fixed-capacitance devices with a constant capacitance and variable capacitors. Variable capacitors are made as trimmers, that are typically adjusted only during circuit calibration, and as a device tunable during operation of the electronic instrument.. The most common group is the fixed capacitors.
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.
