How To Identify Ceramic Disk Capacitors

Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them.

How to identify ceramic disk capacitors.

Ceramic capacitors are usually smaller than your thumb and attach to the circuit with two pins. The first two digits in this case the 10 give us the first part of the value. There are special codes and marking on capacitor which tell about the value of capacitor. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.

The large capacitors in an antique radio typically range from 1 200 µf. Used in many applications they typically range from 1 nf to 1 µf and occasionally up to 100 µf. Mlccs are used instead if capacitance values allow. How to calculate the value of ceramic non polarized capacitors.

Ceramic disc capacitor code label will normally consist of three numbers followed by a letter. The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. Method of finding the value meaning of codes of capacitor. 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.

They are very easy to decode to find the value. The letter j signifies the tolerance of 5. This code indicates what the capacitance of the capacitor is. Then by just using numbers and letters as codes.

To achieve larger capacitances these devices can be made from multiple layers. 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. The third digit is the multiplier which is 1000. The third digit indicates the number of extra zeros in this case 3.

The example capacitor has a 3 digit number printed on it 103. Therefore the capacitance of these two capacitors are 10 and 15 picofarads respectively. Ceramic disc capacitors like the one on the left are printed with a code. Ceramic disc capacitors are manufactured by coating a ceramic disc with silver contacts on both sides.

The first two significant digits represent the first two digits of the actual value which is 47. Ceramic disc capacitors are usually through hole components and are falling out of favor due to their size.
