What does 472 mean on a capacitor?

What does 472 mean on a capacitor?

Use a third digit of 0 through 5 to place the corresponding number of 0s behind the base value. A third digit of 8 means multiply the base value by . 01. A third digit of 9 means to multiply the base value by 0.1. For example, 472 would indicate a 4700 pF capacitor and 479 would indicate a 4.7 pF capacitor.

How do you read a capacitor color coded?

Fig. 3 – An Example to Understand How to Read Capacitor Color Markings

1. The first colour band is Brown. That means the first digit is 1.
2. The second colour band is Red. That means the second digit is 2.
3. The third colour band is Green.
4. The fourth colour band is white.
5. The last colour band is Yellow.

What does 5uf mean on a capacitor?

uF refers to the size of the capacitor. Capacitance is the charge that is necessary to raise the potential of a body one unit. A capacitance of 1 farad (f) requires 1 coulomb of electricity to raise its potential 1 volt (v). 1 micro farad (uF) = 0.0000001 F.

What is color code system of capacitor?

Capacitor Voltage Colour Code Table

What do the colors on a capacitor mean?

The colors painted on the capacitors body are called color bands. All the color bands painted on the capacitors body are used to indicate the capacitance value and capacitance tolerance. Each color painted on the capacitors body represents a different number.

What do the markings on a capacitor mean?

Capacitor Marking. A capacitor marking is a code, which indicates the value of the component. It usually consists of three numbers, which indicates the value, and a letter, which indicates the tolerance. Tables usually provide a means to decode the numbers; however, there are also calculators available as well.

How do you identify ceramic capacitors?

Ceramic types of capacitors generally have a 3-digit code printed onto their body to identify their capacitance value in pico-farads. Generally the first two digits indicate the capacitors value and the third digit indicates the number of zero’s to be added.

What is the value of a capacitor?

Capacitor values can be of over 10 9 range, and even more as super capacitors are now being used. To prevent confusion with large numbers of zeros attached to the values of the different capacitors the common prefixes pico (10 -12 ), nano (10 -9) and micro (10 -6) are widely used.

How do you calculate equivalent capacitance?

The equivalent capacitance for series-connected capacitors can be calculated as 1 / C = 1 / C1 + 1 / C2 + . . + 1 / Cn (2) For the special case with two capacitors in series – the capacitance can be expressed as.
