Ceramic Capacitor Naming Convention

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

Ceramic capacitor naming convention.

Metric units are used for all dimensions. 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. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes. Atc capacitor naming conventions.

A variety of schemes may be used. 47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5. This excludes the bga component family as they only come in the nominal environment condition. Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise.

After the above analysis do you know the naming rules of atc capacitors. 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. Sometimes figures such as 10n will be seen and this indicates a 10nf capacitor. Body sizes and lead span go two places before the decimal point and continue reading ipc 7351b naming convention for.

The ipc 2221a 2222 naming convention for the rlc components begin with res ind or cap which stands for resistor inductor and capacitor respectively. The first number represent the center to center pin distance next is the body length and finally the body width. The first 3 7 characters in the 3d solid model name describe the component kind. A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric.

The first is used with small ceramic capacitors and appears as a single letter. The 3d cad solid electronic modes footprint land pattern naming convention uses component dimensions to describe the 3d electronics part name. Ceramic capacitors are divided into two. Often the value may be given in picofarads.

The first 3 6 characters in the land pattern name describe the component family. Mastering the naming rules is the key to accurately selecting the type of capacitor and the capacitance. Expressed by a letter the meaning is the same as domestic capacitors. Then by just using numbers and letters as codes.

The composition of the ceramic material defines the electrical behavior and therefore applications. The names of domestic capacitors are composed of four parts. The unit is in millimeter mm and it has two significant digits. Library expert naming convention for through hole land patterns the land pattern naming convention uses component dimensions to derive the land pattern name.
