Ceramic Capacitor Naming

Many capacitor manufacturers use a shorthand notation to indicate capacitance on small caps.

Ceramic capacitor naming. The resulting number is the capacitance in pf. T for tantalum 2 3 4. 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 first is used with small ceramic capacitors and appears as a single letter.

The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. Npo type capacitors are frequently used for precision timing filtering frequency setting and tuning circuits. Has a very low dissipation factor and are very stable over wide variations in temperature frequency voltage and time. Method of finding the value meaning of codes of capacitor.

Often the value may be given in picofarads. 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. 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.

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. Here we will discuss tantalum and ceramic part numbers referring to each digit in the part number as a numbered position. Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise. 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. The value of the capacitor is indicated in picofarads. Then by just using numbers and letters as codes. 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.

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

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 capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body.
