How To Find Ceramic Capacitor Value

The example capacitor has a 3 digit number printed on it 103.

How to find ceramic capacitor value.

Multi layer ceramic capacitor mlcc mlccs are manufactured by accurately mixing finely ground granules of paraelectric and ferroelectric materials and alternatively layering the mix with metal contacts. 99 9 of them are not marked at all. The color of the ceramic body material can be sometimes helpful. It s mean that 10 5 zeros 1 000 000 pf.

Below is a very useful chart for calculation the right value of ceramic non polarized capacitors. The first two digits represent the value of the capacitor and the third one the number of zeros to add to the right. How do i identify an smd ceramic capacitor and how do i find its value you don t. When the first two numbers are multiplied with the multiplier the resulting value is the value of the capacitor in picofarads.

The third digit indicates the number of extra zeros in this case 3 extra zeros. 1 c series 1 c 1 1 c 2 1. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. If abc is 104 then the digit 104 means 10 104pf 100000pf 100nf 0 1uf.

If a ceramic capacitor has three digits abc then the value would be ab 10 c pico farad. 100000 pf 100nf. Ceramic disc capacitors have a capacitance value of 10pf to 100μf with a wide variety of voltage ratings between 16 volts to 15 kv and more. There are special codes and marking on capacitor which tell about the value of capacitor.

Like if it says 103 then it means it is 10 uf x 10 3. Class 1 caps np0 c0g ceramics. So the value is 10 with 3 extra zeros or 10 000 ceramic disc capacitor codes are always measured in pico farads or pf. Ceramic disc capacitors have two to three digits code printed on them.

When capacitors are connected in series the equivalent capacitance is given by the following equation. Read the tolerance code on ceramic capacitors. With this we get the capacitor value in picofarads. The ceramic capacitor is labeled as 104.

It may not be possible to have the exact value of desired capacitance in standard e series. Like in the picture the code says 154. The first two digits of printed code are the first two digits of capacitor value and the third digit gives the number of zeroes to be added so as to get capacitor value in pico farad. 4 number of zeros to add.

The first two digits of a ceramic ceramic capacitor tells us the capacitance in uf and the next digit tells us the negative power. Ceramic capacitors which are usually tiny pancakes with two pins typically list the tolerance value as one letter immediately after the three digit capacitance value. In such cases series or parallel combination of capacitors can be used to get the desired capacitance in the circuit. Here is the capacitor marking is 105.

This letter represents the tolerance of the capacitor meaning how close the actual value of the capacitor can be expected to be to the indicated value of the capacitor.
