How To Identify Ceramic Disk Capacitors

Mlccs are used instead if capacitance values allow. Ceramic capacitors are usually smaller than your thumb and attach to the circuit with two pins. Then by just using numbers and letters as codes.

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.

How to identify ceramic disk capacitors.

How to calculate the value of ceramic non polarized capacitors. 47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5. They are very easy to decode to find the value. The example capacitor has a 3 digit number printed on it 103.

The above image shows a pair of ceramic disk capacitors labeled only as 10 and 15 these capacitors and all those under 1000pf directly show their capacitance in picofarads. The first two digits in this case the 10 give us the first part of the value. Ceramic disc capacitor code label will normally consist of three numbers followed by a letter. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.

Method of finding the value meaning of codes of capacitor. The third digit is the multiplier which is 1000. Ceramic disc capacitors are usually through hole components and are falling out of favor due to their size. Ceramic disc capacitors are manufactured by coating a ceramic disc with silver contacts on both sides.

The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. There are special codes and marking on capacitor which tell about the value of capacitor. When the first two numbers are multiplied with the multiplier the. The large capacitors in an antique radio typically range from 1 200 µf.

The third digit indicates the number of extra zeros in this case 3. Therefore the capacitance of these two capacitors are 10 and 15 picofarads respectively. To achieve larger capacitances these devices can be made from multiple layers. Below is a very useful chart for calculation the right value of ceramic non polarized capacitors.

This code indicates what the capacitance of the capacitor is. Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them. The letter j signifies the tolerance of 5. Ceramic disc capacitors like the one on the left are printed with a code.

Used in many applications they typically range from 1 nf to 1 µf and occasionally up to 100 µf. The first two significant digits represent the first two digits of the actual value which is 47.
