Reading Ceramic Capacitor Values

When the first two numbers are multiplied with the multiplier the.

Reading ceramic capacitor values. This letter represents the tolerance of the capacitor meaning how close the actual value of the capacitor can be expected to be. Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them. As they are quite big compared to the rest the value is directly written in the enclosure the value unit is also specified but as they have large capacitance values the chosen unit is the microfarad µf almost 100 of the time even when the unit is smaller i e. If the capacitor code consist only 1 or 2 digits it is simply their capacitance.

How to read capacitance values on a capacitor by doug lowe if there s enough room on the capacitor most manufacturers of electronics components print the capacitance directly on the capacitor along with other information such as the working voltage and perhaps the tolerance. Often the value may be given in picofarads. This is why manufacturers started using a three digit code to mark ceramic capacitors. A 220nf electrolytic capacitor will be labeled as 0 22µf and not 220nf.

Sometimes figures such as 10n will be seen and this indicates a 10nf capacitor. From left to right. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. Ceramic capacitors encoding consists 1 3 digits.

A ceramic disc capacitor does not have a polarity and connects in any direction on the printed circuit board. About ceramic capacitor codes. Method of finding the value meaning of codes of capacitor. By using this capacitor value calculator we can calculate the value of that capacitor or vice versa.

The smaller values in the kit are 50v rated ceramic capacitors. Ceramic capacitors are tiny. Similarly n51 indicates a 0 51nf or 510 pf capacitor etc. For electrolytic capacitors simply capacitance values are written on them.

These are small nonpolarized caps with yellow blob for their body. 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. It s difficult to read their values even with the code. Here is how to read ceramic capacitor values.

Reading values printed on electrolytic capacitors is easy digits on ceramic capacitors need to know some theory. Hence the value of the capacitor above is 47000 pf 5. Smd ceramic capacitor codes. Encoding for ceramic capacitors.

Read the tolerance code on ceramic capacitors. A variety of schemes may be used. Like resistors has some coding which needs to decipher printed digits on ceramic capacitors also needs deciphering. We d need a microscope to read them.

Surface mount capacitors are often very small and do not have the space for markings. Electrolytic capacitors are pretty simple to read.
