Capacitance of the capacitor with a red check mark

What does the marking on a capacitor mean?

Every capacitor has a special marking printed on its body. It represents the value or colour code of capacitor. There are different types of capacitor and each has its specified capacitance value, voltage rating, temperature range, tolerance and life time. But most of the capacitors have their value and their voltage printed on their body.

How do you read the value of a capacitor?

To read the value of a capacitor, the user must consult the markings printed on its body. These markings indicate the capacitance of the capacitor in farads (F) as well as its nominal voltage. Capacitors generally use a capacitance color code similar to the color code of resistors, but sometimes the code is 3 numbers and 1 letter.

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 identify capacitor values & tolerances?

For identifying the capacitor values and tolerances international colour coding scheme (electronic colour coding) was introduced. Every capacitor has colors or alphanumeric characters on the body which indicates the nominal capacitance value of the capacitor. The capacitance can range from 1pico factor to 1 farad.

How do you know if a ceramic disc capacitor is a picofarad?

• Ceramic disc capacitors have two to three digits code printed on them. • The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. • When the first two numbers are multiplied with the multiplier, the resulting value is the value of the capacitor in picofarads.

What are capacitor code values?

A: Capacitor code values are used to represent the capacitance value of a capacitor component. Capacitors are electronic components that store and release electrical energy. The code values help in identifying the capacitance value of a capacitor without having to write the full value in Farads. Q: How are capacitor code values expressed?
