Ceramic Capacitor Marking Guide

25 2020 application guide for true wireless stereo has been released.

Ceramic capacitor marking guide.

These are small nonpolarized caps with yellow blob for their body. The composition of the ceramic material defines the electrical behavior and therefore applications. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes. Let s face it a farad is a lot of capacitance.

In addition to the capacitance value and possibly the working voltage or breakdown voltage the capacitor may be marked by its tolerance. A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric. Capacitor identification capacitor marking review. The two most common types are multi layer ceramic capacitors and ceramic disc capacitors.

Characteristics precision and tolerances. Ceramic disc capacitors have two to three digits code printed on them. Tdk announces new mlccs with world class capacitance for automotive applications sep. 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.

16 2020 application guide for variable frequency drives has been released. 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. There are several tolerance marking systems used. The first is used with small ceramic capacitors and appears as a single letter.

17 2020 application guide for abs cbs in motorcycle has been released. Harry bissell s cap faq is a very detailed guide to selecting capacitors. There are two classes of ceramic capacitors available today. They are very easy to decode to find the value.

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 marking of a bar can be observed in some of the capacitors across their one end denoting the capacitor s polarity. Class 1 and class 2. The first two significant digits represent the first two digits of the actual value which is 47.

The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. Ceramic capacitor definition a ceramic capacitor is a capacitor which uses a ceramic material as the dielectric. The third digit is the multiplier which is 1000. Two of the most common are shown here.
