Ceramic Capicator Marking

Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them.

Ceramic capicator marking.

To get this value you multiply the leading digits 68 in this case by 10 raised to the power of the last digit 3 and the result is the capacitance in picofarads in this case we get 68x10 3 pf. 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 markings on a ceramic capacitor are more concise in nature since it is smaller in size as compared to electrolytic capacitors. American technical ceramics corp.

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. When the first two numbers are multiplied with the multiplier the. In addition to the capacitance value and possibly the working voltage or breakdown voltage the capacitor may be marked by its tolerance.

7 is not. 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. Hence the value of the capacitor above is 47000 pf 5. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.

A variety of schemes may be used. The smallest capacitors made from ceramic film or tantalum use units of picofarads pf equal to 10 12 farads. The first is used with small ceramic capacitors and appears as a single letter. 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.

Sometimes figures such as 10n will be seen and this indicates a 10nf capacitor. Markings of ceramic capacitor. Thus for such concise markings many different types of schemes or solutions are adopted. There are several tolerance marking systems used.

Two of the most common are shown here. There are three exceptions for the last digit. The value of the capacitor is indicated in picofarads. Often the value may be given in picofarads.
