Often the value may be given in picofarads.
Ceramic capicator marking.
If you are new to capacitor codes then the best way to start is with a chart because that way you can see the arrangement of the code.
Hence the value of the capacitor above is 47000 pf 5.
Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them.
The value of the capacitor is indicated in picofarads.
Markings of ceramic capacitor.
The first is used with small ceramic capacitors and appears as a single letter.
Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise.
The top 683 marking indicates the capacitance value which is 68 000 picofarads pf.
The smallest capacitors made from ceramic film or tantalum use units of picofarads pf equal to 10 12 farads.
The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.
Larger capacitors the cylindrical aluminum electrolyte type or the double layer type use units of microfarads uf or µf equal to 10 6 farads.
A variety of schemes may be used.
There are several tolerance marking systems used.
American technical ceramics corp.
There are three exceptions for the last digit.
7 is not.
Two of the most common are shown here.
Method of finding the value meaning of codes of capacitor.
A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric it is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes the composition of the ceramic material defines the electrical behavior and therefore applications.
Thus for such concise markings many different types of schemes or solutions are adopted.
When the first two numbers are multiplied with the multiplier the.
Sometimes figures such as 10n will be seen and this indicates a 10nf capacitor.
Atc provides component and custom integrated packaging solutions for the rf microwave and telecommunications industries atc designs develops manufactures and markets multilayer capacitors single layer capacitors resistive products inductors and custom thin film products for rf microwave and millimeter wave applications.
The above image shows a mylar film capacitor.
In addition to the capacitance value and possibly the working voltage or breakdown voltage the capacitor may be marked by its tolerance.
