To express those small values succinctly we use the metric system.
Ceramic capacitor value identification.
Capacitor values are usually tiny often in the millionths or billionths of a farad.
When the first two numbers are multiplied with the multiplier the resulting value is the value of the capacitor in picofarads.
Characteristics precision and tolerances.
Capacitor identification capacitor marking review.
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.
Let s face it a farad is a lot of capacitance.
Class 1 and class 2.
47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5.
Ceramic capacitor definition a ceramic capacitor is a capacitor which uses a ceramic material as the dielectric.
Then by just using numbers and letters as codes.
The following prefixes are the modern convention.
The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body.
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.
The two most common types are multi layer ceramic capacitors and ceramic disc capacitors.
The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.
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.
