Ceramic Capacitor Value Identification

A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric it is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes the composition of the ceramic material defines the electrical behavior and therefore applications.

Ceramic capacitor value identification.

The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. Ceramic disc capacitors have two to three digits code printed on them. The following prefixes are the modern convention. Capacitor identification capacitor marking review.

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. There are two classes of ceramic capacitors available today. The two most common types are multi layer ceramic capacitors and ceramic disc capacitors. 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.

To express those small values succinctly we use the metric system. 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. 47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5.

Capacitor values are usually tiny often in the millionths or billionths of a farad. Let s face it a farad is a lot of capacitance. The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. Class 1 and class 2.
