Ceramic Capacitor Value Identification

Class 1 and class 2.

Ceramic capacitor value identification.

Then by just using numbers and letters as codes. Ceramic disc capacitors have two to three digits code printed on them. The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. Ceramic capacitor definition a ceramic capacitor is a capacitor which uses a ceramic material as the dielectric.

There are two classes of ceramic capacitors available today. Capacitor values are usually tiny often in the millionths or billionths of a farad. 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.

Let s face it a farad is a lot of capacitance. Characteristics precision and tolerances. 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. The two most common types are multi layer ceramic capacitors and ceramic disc capacitors.

Capacitor identification capacitor marking review. To express those small values succinctly we use the metric system. The following prefixes are the modern convention. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.
