Ceramic Capacitor Naming Convention

Mastering the naming rules is the key to accurately selecting the type of capacitor and the capacitance.

Ceramic capacitor naming convention.

Expressed by a letter the meaning is the same as domestic capacitors. Ceramic capacitors are divided into two. The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. Then by just using numbers and letters as codes.

47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5. Often the value may be given in picofarads. This excludes the bga component family as they only come in the nominal environment condition. The first is used with small ceramic capacitors and appears as a single letter.

The unit is in millimeter mm and it has two significant digits. The model names of capacitors in different countries are not uniform. The names of domestic capacitors are composed of four parts. The first number represent the center to center pin distance next is the body length and finally the body width.

A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric. The 3d cad solid electronic modes footprint land pattern naming convention uses component dimensions to describe the 3d electronics part name. The first 3 7 characters in the 3d solid model name describe the component kind. A variety of schemes may be used.

Library expert naming convention for through hole land patterns the land pattern naming convention uses component dimensions to derive the land pattern name. Use letters to indicate the name and the capacitor is c. After the above analysis do you know the naming rules of atc capacitors. The ipc 2221a 2222 naming convention for the rlc components begin with res ind or cap which stands for resistor inductor and capacitor respectively.

Body sizes and lead span go two places before the decimal point and continue reading ipc 7351b naming convention for. The first 3 6 characters in the land pattern name describe the component family. Ipc 7351b suffix naming convention for land patterns common smt land pattern to describe environment use this is the last character in every name note. 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.

Metric units are used for all dimensions. The composition of the ceramic material defines the electrical behavior and therefore applications. Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise. Atc capacitor naming conventions.
