Ceramic Capacitor Markings

The first two significant digits represent the first two digits of the actual value which is 47.

Ceramic capacitor markings. Often the value may be given in picofarads. Expressed differently this is 0 0001 farads. 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. Typical markings let s examine some typical capacitor markings.

Sometimes figures such as 10n will be seen and this indicates a 10nf capacitor. Unlike ceramics they are polarized. Two of the most common are shown here. Tables usually provide a means to decode the numbers.

Click here for resistor colour code and smd resistor code. A variety of schemes may be used. The first is used with small ceramic capacitors and appears as a single letter. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.

There are several tolerance marking systems used. They are very easy to decode to find the value. 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. From left to right.

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 disc capacitors have two to three digits code printed on them. However there are also calculators available as well. Ceramic disc capacitor code label will normally consist of three numbers followed by a letter.

1µf 10µf 100µf 1000µf the markings on the lytic caps are easily legible the value and units are printed right on the body. The markings on a ceramic capacitor are more concise in nature since it is smaller in size as compared to electrolytic capacitors. It usually consists of three numbers which indicates the value and a letter which indicates the tolerance. The value is followed with the voltage rating indicating the maximum dc potential that the cap can withstand without damage.

Capacitor marking a capacitor marking is a code which indicates the value of the component. Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise. When the first two numbers are multiplied with the multiplier the resulting value is the value of the capacitor in picofarads. Markings of ceramic capacitor.

The third digit is the multiplier which is 1000.
