What should a capacitor's voltage rating be?

Apart from nominal capacitance, the voltage rating is the second most important parameter that must be essentially factored in. The capacitor’s voltage rating should always be at least 1.5 times or twice the maximum voltage it may encounter in the circuit. Capacitors are not as reliable as resistors.

What does a color code mean on a capacitor?

In the past, color codes and different types of numerical codes were used to indicate value, tolerance, and working voltage of capacitors. Today, the capacitance, tolerance, and working voltage are printed on the body of the capacitors or indicated by BS1852 standard or BS EN 60062 standard codes.

How do you know if a capacitor is working?

Today, the capacitance, tolerance, and working voltage are printed on the body of the capacitors or indicated by BS1852 standard or BS EN 60062 standard codes. In these coding systems, the value, tolerance, and working voltage of the capacitor are indicated by two -or three-digit numerical codes followed by a letter.

Why do capacitors use tolerance codes?

Capacitors use tolerance codes, much like resistors, standardized by the Electronic Industry Alliance (EIA). These codes indicate how much the actual capacitance may deviate from the marked value. This precision is ideal for designing and maintaining high-accuracy circuits.

What factors should be considered when choosing a capacitor?

Apart from the suitability of different capacitors for specific applications, other important factors that may need to consider include the following: Tolerance – It must be checked if the working of the circuit depends on precision capacitance. A capacitor with the lowest tolerance should be used if it requires narrow capacitance.
