How To Read Ceramic Capacitor 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.

How to read ceramic capacitor codes.

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. This letter represents the tolerance of the capacitor meaning how close the actual value of the capacitor can be expected to be. Ceramic capacitors are tiny. Ceramic capacitor codes how to read a ceramic capacitor with numeric coding.

This is why manufacturers started using a three digit code to mark ceramic capacitors. When the first two numbers are multiplied with the multiplier the. Then by just using numbers and letters as codes. 47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5.

Some of these markings and codes include capacitor polarity marking. Multiplier table ceramic number multiply by additional of zeros 0 none 0 1 10 1. Method of finding the value meaning of codes of capacitor. Read the tolerance code on ceramic capacitors.

About ceramic capacitor codes. The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them. The various parameters of the capacitors such as their voltage and tolerance along with their values is represented by different types of markings and codes.

We d need a microscope to read them. Capacitor codes and associated markings. 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. It s difficult to read their values even with the code.

And ceramic capacitor code respectively.
