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.

Expressed differently this is 0 0001 farads. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. The third digit is the multiplier which is 1000. 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. 1µf 10µf 100µf 1000µf the markings on the lytic caps are easily legible the value and units are printed right on the body. Capacitor marking a capacitor marking is a code which indicates the value of the component. Thus for such concise markings many different types of schemes or solutions are adopted.

Tables usually provide a means to decode the numbers. Unlike ceramics they are polarized. They are very easy to decode to find the value. From left to right.

Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise. It usually consists of three numbers which indicates the value and a letter which indicates the tolerance. When the first two numbers are multiplied with the multiplier the resulting value is the value of the capacitor in picofarads. 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.

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. The first two significant digits represent the first two digits of the actual value which is 47. However there are also calculators available as well. Two of the most common are shown here.

There are several tolerance marking systems used. Often the value may be given in picofarads. Ceramic disc capacitor code label will normally consist of three numbers followed by a letter. Typical markings let s examine some typical capacitor markings.

The first is used with small ceramic capacitors and appears as a single letter.
