Ceramic disc capacitor code/label will normally consist of three numbers followed by a letter. They are very easy to decode to find the value. The first two significant digits represent the first two digits of the actual value, which is 47. The third digit is the multiplier, which is ×1000. The letter J signifies the tolerance of ±5 %. Since this is the EIA coding system, the value will be in picofarads. Hence the value of the capacitor above is 47000 pF ±5 %. A ceramic disc capacitor does not have a polarity and connects in any direction on the printed circuit board. 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. Engineers usually do not require calculators because the code is so simple. Here is another example, code 104 is 10 followed by four zeros, hence 10 0000 pF. Note: This capacitor box doesn’t come with the exact components as printed on its label in the image, We source these items from different vendors across India the quality and quantity vary in every lot and we sell it as it is without verification of the items inside it.
