Ceramic Capacitor Markings

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.

Ceramic capacitor markings.

Ceramic disc capacitor code label will normally consist of three numbers followed by a letter. It usually consists of three numbers which indicates the value and a letter which indicates the tolerance. However there are also calculators available as well. Sometimes figures such as 10n will be seen and this indicates a 10nf capacitor.

The value of the capacitor is indicated in picofarads. The markings on a ceramic capacitor are more concise in nature since it is smaller in size as compared to electrolytic capacitors. 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.

Expressed differently this is 0 0001 farads. 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. Click here for resistor colour code and smd resistor code. The first two significant digits represent the first two digits of the actual value which is 47.

Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise. A variety of schemes may be used. They are very easy to decode to find the value. Typical markings let s examine some typical capacitor markings.

The value is followed with the voltage rating indicating the maximum dc potential that the cap can withstand without damage. The third digit is the multiplier which is 1000. Thus for such concise markings many different types of schemes or solutions are adopted. Capacitor marking a capacitor marking is a code which indicates the value of the component.

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. 1µf 10µf 100µf 1000µf the markings on the lytic caps are easily legible the value and units are printed right on the body. Unlike ceramics they are polarized. Two of the most common are shown here.

The first is used with small ceramic capacitors and appears as a single letter. There are several tolerance marking systems used. Markings of ceramic capacitor. Ceramic disc capacitors have two to three digits code printed on them.
