How is the capacitance value of a ceramic disc capacitor identified?
Ceramic disc capacitors like the one on the left are printed with a code. This code indicates what the capacitance of the capacitor is. The example capacitor has a 3 digit number printed on it (103). The third digit indicates the number of extra zeros, in this case 3 extra zeros.
What is the value of ceramic disk capacitor?
Ceramic capacitors are usually made with very small capacitance values, typically between 1nF and 1µF, although values up to 100µF are possible.
How to find the capacitor on a ceramic disc?
Ceramic Disc Capacitor Values / Code / Label. 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.
What are the numbers on a ceramic disc label?
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.
What is the tolerance of a ceramic capacitor?
The letter J signifies the tolerance of ±5 %. Since this is the EIA coding system, the value will be in pico farads. 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.
How to read the value of a capacitor?
• When the first two numbers are multiplied with the multiplier, the resulting value is the value of the capacitor in picofarads. • If there is only two number, it means there is no multiplier, Then you just read the value of the first two numbers in picofarads.
