Reading Ceramic Capacitor Code

Similarly if the capacitor code is 152 the 3 rd digit is 2 so multiplier factor is 100.

Reading ceramic capacitor code. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. Multiplier table ceramic number multiply by additional of zeros 0 none 0 1 10 1. So this is how a capacitor value code calculator calculates the ceramic capacitor value from the capacitor code or vice versa. 15 100 1500 pf.

Smd ceramic capacitor codes. The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. Ceramic capacitor codes how to read a ceramic capacitor with numeric coding. 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.

Sometimes figures such as 10n will be seen and this indicates a 10nf capacitor. Often the value may be given in picofarads. Similarly n51 indicates a 0 51nf or 510 pf capacitor etc. 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.

A variety of schemes may be used. 47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5. This letter represents the tolerance of the capacitor meaning how close the actual value of the capacitor can be expected to be. Read the tolerance code on ceramic capacitors.

Surface mount capacitors are often very small and do not have the space for markings. The capacitance value will be calculated as follows. When the first two numbers are multiplied with the multiplier the.
