Ceramic Capacitor Marking 103

The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body.

Ceramic capacitor marking 103. There are several tolerance marking systems used. Then by just using numbers and letters as codes. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. 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.

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. Often the value may be given in picofarads. Two of the most common are shown here.

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. When the first two numbers are multiplied with the multiplier the. A ceramic disc capacitor does not have a polarity and connects in any direction on the printed circuit board. Hence the value of the capacitor above is 47000 pf 5.

Larger capacitors the cylindrical aluminum electrolyte type or the double layer type use units of microfarads uf or µf equal to 10 6 farads. Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them. Method of finding the value meaning of codes of capacitor. 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. Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise. In addition to the capacitance value and possibly the working voltage or breakdown voltage the capacitor may be marked by its tolerance. 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.

47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5. 103 ceramic disc capacitors are available at mouser electronics.
