Ceramic Capacitor Markings

The third digit is the multiplier which is 1000.

Ceramic capacitor markings.

The first two significant digits represent the first two digits of the actual value which is 47. 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. Thus for such concise markings many different types of schemes or solutions are adopted.

This letter represents the tolerance of the capacitor meaning how close the actual value of the capacitor can be expected to be to the indicated value of the capacitor. There are several tolerance marking systems used. The markings on a ceramic capacitor are more concise in nature since it is smaller in size as compared to electrolytic capacitors. Often the value may be given in picofarads.

Expressed differently this is 0 0001 farads. Ceramic disc capacitor code label will normally consist of three numbers followed by a letter. Unlike ceramics they are polarized. Typical markings let s examine some typical capacitor markings.

When the first two numbers are multiplied with the multiplier the resulting value is the value of the capacitor in picofarads. Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise. From left to right. The first is used with small ceramic capacitors and appears as a single letter.

They are very easy to decode to find the value. The value of the capacitor is indicated in picofarads. Ceramic capacitors which are usually tiny pancakes with two pins typically list the tolerance value as one letter immediately after the three digit capacitance value. Markings of ceramic capacitor.

1µf 10µf 100µf 1000µf the markings on the lytic caps are easily legible the value and units are printed right on the body. The value is followed with the voltage rating indicating the maximum dc potential that the cap can withstand without damage. A variety of schemes may be used. However there are also calculators available as well.

The image above is of an electrolytic capacitor marked with 100μf meaning it has a capacitance of 100 microfarads the μ prefix indicates 10 6. Two of the most common are shown here.

Capacitor tolerance markings in addition to the capacitance value and possibly the working voltage or breakdown voltage the capacitor may be marked by its tolerance.
