Ceramic Capacitor Markings

However there are also calculators available as well.

Ceramic capacitor markings.

Often the value may be given in picofarads. The third digit is the multiplier which is 1000. Sometimes figures such as 10n will be seen and this indicates a 10nf capacitor. The first is used with small ceramic capacitors and appears as a single letter.

A variety of schemes may be used. 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 value of the capacitor is indicated in picofarads. Expressed differently this is 0 0001 farads.

The markings on a ceramic capacitor are more concise in nature since it is smaller in size as compared to electrolytic capacitors. There are several tolerance marking systems used. Unlike ceramics they are polarized. Thus for such concise markings many different types of schemes or solutions are adopted.

The value is followed with the voltage rating indicating the maximum dc potential that the cap can withstand without damage. 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 capacitors have two to three digits code printed on them. 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.

It usually consists of three numbers which indicates the value and a letter which indicates the tolerance. Ceramic disc capacitor code label will normally consist of three numbers followed by a letter. Typical markings let s examine some typical capacitor markings. Capacitor marking a capacitor marking is a code which indicates the value of the component.

Tables usually provide a means to decode the numbers. From left to right. 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. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.

Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise. Markings of ceramic capacitor. Click here for resistor colour code and smd resistor code. Two of the most common are shown here.

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