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.

To express those small values succinctly we use the metric system. Then by just using numbers and letters as codes. The two most common types are multi layer ceramic capacitors and ceramic disc capacitors. Ceramic disc capacitors have two to three digits code printed on them.

Capacitor identification capacitor marking review. Ceramic capacitor definition a ceramic capacitor is a capacitor which uses a ceramic material as the dielectric. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. 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.

The following prefixes are the modern convention. When the first two numbers are multiplied with the multiplier the resulting value is the value of the capacitor in picofarads. The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. There are two classes of ceramic capacitors available today.

Class 1 and class 2. Characteristics precision and tolerances. Let s face it a farad is a lot of capacitance. Capacitor values are usually tiny often in the millionths or billionths of a farad.
