How To Identify Ceramic Disk Capacitors

When the first two numbers are multiplied with the multiplier the.

How to identify ceramic disk capacitors.

Therefore the capacitance of these two capacitors are 10 and 15 picofarads respectively. Used in many applications they typically range from 1 nf to 1 µf and occasionally up to 100 µf. Ceramic disc capacitors are manufactured by coating a ceramic disc with silver contacts on both sides. This code indicates what the capacitance of the capacitor is.

The letter j signifies the tolerance of 5. Ceramic disc capacitors like the one on the left are printed with a code. How to calculate the value of ceramic non polarized capacitors. 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.

There are special codes and marking on capacitor which tell about the value of capacitor. Below is a very useful chart for calculation the right value of ceramic non polarized capacitors. To achieve larger capacitances these devices can be made from multiple layers. The first two significant digits represent the first two digits of the actual value which is 47.

They are very easy to decode to find the value. The example capacitor has a 3 digit number printed on it 103. Ceramic disc capacitors are usually through hole components and are falling out of favor due to their size. Mlccs are used instead if capacitance values allow.

Ceramic capacitors are usually smaller than your thumb and attach to the circuit with two pins. 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 first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.

Then by just using numbers and letters as codes. The third digit is the multiplier which is 1000. 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.

The first two digits in this case the 10 give us the first part of the value. Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them.
