Ceramic Capacitor Naming

Has a very low dissipation factor and are very stable over wide variations in temperature frequency voltage and time.

Ceramic capacitor naming.

Method of finding the value meaning of codes of capacitor. 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. 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.

47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5. Sometimes figures such as 10n will be seen and this indicates a 10nf capacitor. Here we will discuss tantalum and ceramic part numbers referring to each digit in the part number as a numbered position. 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.

When the first two numbers are multiplied with the multiplier the. 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. Kemet tantalum part number t 110 a 105 k 0 3 5 a s 1 2 3 4 5 6 7 8 9 10 11 12 13 14 position 1.

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. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. Often the value may be given in picofarads. Npo type capacitors are frequently used for precision timing filtering frequency setting and tuning circuits.

T for tantalum 2 3 4. Many capacitor manufacturers use a shorthand notation to indicate capacitance on small caps. The resulting number is the capacitance in pf. Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise.

The value of the capacitor is indicated in picofarads. Markings of ceramic capacitor. Then by just using numbers and letters as codes. The second is used for a variety of capacitor types and is indicated by a unique assortment of lettrs and numbers which represent the low and high temperature requirements the lower and upper acceptable temperature range of operating the capacitor and its.

Thus for such concise markings many different types of schemes or solutions are adopted. The markings on a ceramic capacitor are more concise in nature since it is smaller in size as compared to electrolytic capacitors.
