Reading Ceramic Capacitor Code

A variety of schemes may be used.

Reading ceramic capacitor code.

Read the tolerance code on ceramic capacitors. The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. Surface mount capacitors are often very small and do not have the space for markings. Method of finding the value meaning of codes of capacitor.

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. Multiplier table ceramic number multiply by additional of zeros 0 none 0 1 10 1. Ceramic capacitor codes how to read a ceramic capacitor with numeric coding. Often the value may be given in picofarads.

Then by just using numbers and letters as codes. Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them. So this is how a capacitor value code calculator calculates the ceramic capacitor value from the capacitor code or vice versa. The capacitance value will be calculated as follows.

This letter represents the tolerance of the capacitor meaning how close the actual value of the capacitor can be expected to be. 47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. Similarly n51 indicates a 0 51nf or 510 pf capacitor etc.

15 100 1500 pf. Similarly if the capacitor code is 152 the 3 rd digit is 2 so multiplier factor is 100. Sometimes figures such as 10n will be seen and this indicates a 10nf capacitor.
