Ceramic Capacitor Markings

The value is followed with the voltage rating indicating the maximum dc potential that the cap can withstand without damage.

Ceramic capacitor markings.

Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise. There are several tolerance marking systems used. 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. Capacitor marking a capacitor marking is a code which indicates the value of the component.

However there are also calculators available as well. Two of the most common are shown here. Markings of ceramic capacitor. A variety of schemes may be used.

It usually consists of three numbers which indicates the value and a letter which indicates the tolerance. 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. Unlike ceramics they are polarized. The markings on a ceramic capacitor are more concise in nature since it is smaller in size as compared to electrolytic capacitors.

Sometimes figures such as 10n will be seen and this indicates a 10nf capacitor. The first two significant digits represent the first two digits of the actual value which is 47. Click here for resistor colour code and smd resistor code. Ceramic disc capacitors have two to three digits code printed on them.

The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. 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. 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. Ceramic disc capacitor code label will normally consist of three numbers followed by a letter.

Expressed differently this is 0 0001 farads. When the first two numbers are multiplied with the multiplier the resulting value is the value of the capacitor in picofarads. The first is used with small ceramic capacitors and appears as a single letter. They are very easy to decode to find the value.

Typical markings let s examine some typical capacitor markings. Tables usually provide a means to decode the numbers. The value of the capacitor is indicated in picofarads. 1µf 10µf 100µf 1000µf the markings on the lytic caps are easily legible the value and units are printed right on the body.

Often the value may be given in picofarads.
