What do the coloured bands on a capacitor mean?
These coloured bands represent the capacitance value as per the colour code including voltage rating and tolerance. Sometimes the actual values of capacitance, voltage or tolerance are marked onto the body of a capacitor in the form of alphanumeric characters.
How do you know if a capacitor is capacitive?
There are two common ways to know the capacitive value of a capacitor, by measuring it using a digital multimeter, or by reading the capacitor colour codes printed on it. These coloured bands represent the capacitance value as per the colour code including voltage rating and tolerance.
How to read PCB capacitor polarity markings?
Here’s how to read PCB capacitor polarity markings: Check for the “+” and “-“ symbols next to the capacitor pads. These markings directly indicate where to place the positive and negative leads of the capacitor. For many polarized capacitors, the negative pad is usually smaller than the positive pad.
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.
