I hope you get a lot from the reading, if so, kindly share with other students.Size Chart - Footprint Selection chart - TopLine Dummy Component Foot Print Cross Reference. That is all for this article where the color codes of capacitors have been discussed.
Read more: Understanding the dielectric of a capacitor Watch the video below to learn the color code of capacitors: The table below shows the international codes for pico-Farad’s, Nano-farads, or Micro-farads and their equivalent capacitance. All of these international codes are given in the following table and their equivalent capacitance. Their capacitance values are either in pico-Farad’s, Nano-farads, or Micro-farads.
Now you can see using numbers and letters as codes on the body of capacitors makes it easy to determine their value.

So, the 4 is the 1 st digit, 7 is the 2 nd digit, and the 3 is the multiplier in pico-Farads, pF, and the letter J is the tolerance. The table below shows the capacitor tolerance latter codes:Ĭonsider the capacitor below, it is a ceramic disc type that has the code 473J labeled on its body.
You should know that three-digit codes are often accompanied by an additional tolerance latter code. Let take for instance, the digits 471 = 47*10 = 470pF. For a three later code, it consists of two value digits and a multiplier just like the resistor color codes in the resistors section. When two number code is used, the value of the capacitor is given in picofarads, for example, 47 = 47pF and 100 = 100pF, etc. Normally, the code is of 2 or 3 numbers and an optional tolerance letter code to identify the tolerance. The color system has been replaced by a latter or number-coded system. Nowadays, capacitors such as disk and film types conform to the BS1852 standard and its new replacement, BS EN 60062. But there are still many old capacitors around which is why the color code system is still necessary. It was employed a long time ago on unpolarized polyester and mica molded capacitors. However, the capacitor color code system is not present in use.

It was developed many years ago as a simple way of identifying capacitor values and tolerances. The confusion of the labeled letters, numbers, and decimal points can reduce by using the international color-coding scheme. Also, capacitors are sometimes marked with the capital letter K to signify a value of one thousand pico-Farads, so, a capacitor of 100K would be 100 x 1000pF or 100nF. Let take for instance, a capacitor can be marked as, n47 = 0.47nF, 4n7 = 4.7nF or 47n = 47nF and so on. Instead of letters like p (pico) or n (nano), decimal points are used to identify the position and the weight of the number. This will result in a misreading of the actual capacitance value. When a value of capacitance is marked as a decimal value, the decimal point will not be easily noticed. These color codes indicate the value of capacitance, voltage, and tolerance of the capacitor.
The color codes of capacitors are marked on their body so that they can be easily characterized and understand by electricians.
