Ceramic Capacitor Marking Guide

When the first two numbers are multiplied with the multiplier the resulting value is the value of the capacitor in picofarads.

Ceramic capacitor marking guide. 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. Ceramic disc capacitor code label will normally consist of three numbers followed by a letter. Characteristics precision and tolerances. There are two classes of ceramic capacitors available today.

The composition of the ceramic material defines the electrical behavior and therefore applications. The first is used with small ceramic capacitors and appears as a single letter. Ceramic disc capacitors have two to three digits code printed on them. Let s face it a farad is a lot of capacitance.

The marking of a bar can be observed in some of the capacitors across their one end denoting the capacitor s polarity. 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. 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. The smaller values in the kit are 50v rated ceramic capacitors.

Capacitor identification capacitor marking review. The third digit is the multiplier which is 1000. 25 2020 application guide for true wireless stereo has been released. The two most common types are multi layer ceramic capacitors and ceramic disc capacitors.

Two of the most common are shown here. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric. Harry bissell s cap faq is a very detailed guide to selecting capacitors.

There are several tolerance marking systems used. 17 2020 application guide for abs cbs in motorcycle has been released. Class 1 and class 2. Ceramic capacitor definition a ceramic capacitor is a capacitor which uses a ceramic material as the dielectric.

They are very easy to decode to find the value. Tdk announces new mlccs with world class capacitance for automotive applications sep. 16 2020 application guide for variable frequency drives has been released. The first two significant digits represent the first two digits of the actual value which is 47.
