Ceramic Capacitor Naming

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

Ceramic capacitor naming.

Markings of ceramic capacitor. Then by just using numbers and letters as codes. 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. Series is a three digit number which is the name of a part with certain specifications.

The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. 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. Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them. The first is used with small ceramic capacitors and appears as a single letter.

Npo type capacitors are frequently used for precision timing filtering frequency setting and tuning circuits. The resulting number is the capacitance in pf. 47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5. Thus for such concise markings many different types of schemes or solutions are adopted.

Often the value may be given in picofarads. Has a very low dissipation factor and are very stable over wide variations in temperature frequency voltage and time. A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric it is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes the composition of the ceramic material defines the electrical behavior and therefore applications. Sometimes figures such as 10n will be seen and this indicates a 10nf capacitor.

When the first two numbers are multiplied with the multiplier the. If you have a capacitor that has nothing other than a three digit number printed on it the third digit represents the number of zeros to add to the end of the first two digits. A variety of schemes may be used. Many capacitor manufacturers use a shorthand notation to indicate capacitance on small caps.

Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise. Then the 4 1 st digit the 7 2 nd digit the 3 is the multiplier in pico farads pf and the letter j is the tolerance and this translates to. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. The value of the capacitor is indicated in picofarads.
