Read Ceramic Capacitor Codes

Read the tolerance code on ceramic capacitors.

Read ceramic capacitor codes. 15 100 1500 pf. Ceramic capacitor codes how to read a ceramic capacitor with numeric coding. Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them. 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. 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 many instances where the capacitor is small no voltage coding is provided and care must be taken when using a capacitor without any knowledge of its working voltage.

The capacitance value will be calculated as follows. Multiplier table ceramic number multiply by additional of zeros 0 none 0 1 10 1. When the first two numbers are multiplied with the multiplier the. Similarly if the capacitor code is 152 the 3 rd digit is 2 so multiplier factor is 100.

The working voltage for a capacitor is very important and therefore this parameter is often marked on capacitors and particularly in situations where there is space for alphanumeric coding. The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. 47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5. 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.
