Ceramic Capacitor Marking 103

Method of finding the value meaning of codes of capacitor.

Ceramic capacitor marking 103.

Larger capacitors the cylindrical aluminum electrolyte type or the double layer type use units of microfarads uf or µf equal to 10 6 farads. Then by just using numbers and letters as codes. The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. Then the 4 1 st digit the 7 2 nd digit the 3 is the multiplier in pico farads pf and the letter j is the tolerance and this translates to.

Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise. When the first two numbers are multiplied with the multiplier the. Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them. Mouser offers inventory pricing datasheets for 103 ceramic disc capacitors.

In addition to the capacitance value and possibly the working voltage or breakdown voltage the capacitor may be marked by its tolerance. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. 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. A ceramic disc capacitor does not have a polarity and connects in any direction on the printed circuit board.

This is a simple online calculator for color band resistor marking inductor color band marking ceramic or tantalum capacitor 3 digit marking and smd resistor 3 digit 4 digit 10 5 2 and eia 96 e96 1 tolerance code marking. The 3 digit capacitor code 103 stands for 10 nf in words. Often the value may be given in picofarads. 103 ceramic disc capacitors are available at mouser electronics.

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. Common ceramic capacitor tags capacitor 108 0 1 pf capacitor 158 0 15 pf capacitor 228 0 22 pf capacitor 338 0 33 pf capacitor 478 0 47 pf. Hence the value of the capacitor above is 47000 pf 5.

Sometimes figures such as 10n will be seen and this indicates a 10nf capacitor. Two of the most common are shown here.
