Ceramic Capacitor Naming Convention

Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise.

Ceramic capacitor naming convention.

Metric units are used for all dimensions. 47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5. Body sizes and lead span go two places before the decimal point and continue reading ipc 7351b naming convention for. Then by just using numbers and letters as codes.

A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric. 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. Library expert naming convention for through hole land patterns the land pattern naming convention uses component dimensions to derive the land pattern name. 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.

A variety of schemes may be used. Atc capacitor naming conventions. 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. The 3d cad solid electronic modes footprint land pattern naming convention uses component dimensions to describe the 3d electronics part name.

Expressed by a letter the meaning is the same as domestic capacitors. The names of domestic capacitors are composed of four parts. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes. After the above analysis do you know the naming rules of atc capacitors.

This excludes the bga component family as they only come in the nominal environment condition. The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. Ceramic capacitors are divided into two. 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 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 composition of the ceramic material defines the electrical behavior and therefore applications.

Mastering the naming rules is the key to accurately selecting the type of capacitor and the capacitance. The first 3 7 characters in the 3d solid model name describe the component kind. Sometimes figures such as 10n will be seen and this indicates a 10nf capacitor. Use letters to indicate the name and the capacitor is c.
