Ceramic Capicator Marking

Thus for such concise markings many different types of schemes or solutions are adopted.

Ceramic capicator marking.

The top 683 marking indicates the capacitance value which is 68 000 picofarads pf. 7 is not. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. In addition to the capacitance value and possibly the working voltage or breakdown voltage the capacitor may be marked by its tolerance.

The smallest capacitors made from ceramic film or tantalum use units of picofarads pf equal to 10 12 farads. Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them. The markings on a ceramic capacitor are more concise in nature since it is smaller in size as compared to electrolytic capacitors. 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.

Markings of ceramic capacitor. A ceramic disc capacitor does not have a polarity and connects in any direction on the printed circuit board. The first is used with small ceramic capacitors and appears as a single letter. 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.

The value of the capacitor is indicated in picofarads. Hence the value of the capacitor above is 47000 pf 5. American technical ceramics corp. A variety of schemes may be used.

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. There are three exceptions for the last digit. Sometimes figures such as 10n will be seen and this indicates a 10nf capacitor. Often the value may be given in picofarads.

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. Two of the most common are shown here. Larger capacitors the cylindrical aluminum electrolyte type or the double layer type use units of microfarads uf or µf equal to 10 6 farads. When the first two numbers are multiplied with the multiplier the.
