Ceramic Capacitor Naming Convention

These units are the modern convention and mostly follow the guidelines for applying the metric system.

Ceramic capacitor naming convention.

47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5. These are the capacitors that you ll likely be working with on your first electronics project using a breadboard. A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric. They also happen to be the cheapest capacitor of the bunch so stock up.

This code is similar to the color code. You can quickly identify a through hole ceramic capacitor by looking for the. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes. From left to right.

While in case the capacitor is of aluminium electrolytes microfarads is used to denote the capacitor s value. The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. The unit is in millimeter mm and it has two significant digits. The smaller values in the kit are 50v rated ceramic capacitors.

10 pf 22 pf 100 pf 1 nf 10 nf 100 nf. The convention is in sympathy with component names used in the ipc sm 782a standard and closely follows the jedec standard descriptive designation system for semiconductor device packages jesd30 b april 1995. Bga pin qty c or n col pitch x row pitch p ball columns x ball rows body length x body width x height bga w staggered. The ipc 2221a 2222 naming convention for the rlc components begin with res ind or cap which stands for resistor inductor and capacitor respectively.

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. These are small nonpolarized caps with yellow blob for their body. Bga pin qty c or n pitch p ball columns x ball rows body length x body width x height bga w dual pitch. The naming system is based upon a minimum compulsory code that describes the package outline style.

Ceramic capacitors are divided into two application classes. 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 composition of the ceramic material defines the electrical behavior and therefore applications. Unlike their electrolytic counterparts ceramic capacitors hold a smaller charge but also leak less current.

The first number represent the center to center pin distance next is the body length and finally the body width. Class 1 ceramic capacitors. The value is printed on each in a three digit code.
