Ceramic Capacitor Marking Guide

Ceramic disc capacitor code label will normally consist of three numbers followed by a letter.

Ceramic capacitor marking guide.

In addition to the capacitance value and possibly the working voltage or breakdown voltage the capacitor may be marked by its tolerance. There are two classes of ceramic capacitors available today. A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric. 25 2020 application guide for true wireless stereo has been released.

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 smaller values in the kit are 50v rated ceramic capacitors. Let s face it a farad is a lot of capacitance. 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.

17 2020 application guide for abs cbs in motorcycle has been released. Characteristics precision and tolerances. The third digit is the multiplier which is 1000. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes.

The marking format consist of three figures is generally used for the capacitors which has sufficient space available such as is evident in the ceramic capacitors. Tdk announces new mlccs with world class capacitance for automotive applications sep. The first two significant digits represent the first two digits of the actual value which is 47. Class 1 and class 2.

The two most common types are multi layer ceramic capacitors and ceramic disc capacitors. These are small nonpolarized caps with yellow blob for their body. 16 2020 application guide for variable frequency drives has been released. They are very easy to decode to find the value.

Ceramic capacitor definition a ceramic capacitor is a capacitor which uses a ceramic material as the dielectric. There are several tolerance marking systems used. Ceramic disc capacitors have two to three digits code printed on them. The first is used with small ceramic capacitors and appears as a single letter.

Harry bissell s cap faq is a very detailed guide to selecting capacitors. When the first two numbers are multiplied with the multiplier the resulting value is the value of the capacitor in picofarads. Capacitor identification capacitor marking review. The composition of the ceramic material defines the electrical behavior and therefore applications.
