6 FAQs about [Ceramic capacitor field]
What is a ceramic capacitor?
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.
What is a fixed value ceramic capacitor?
A fixed-value ceramic capacitor uses a ceramic material as the dielectric. It comprises two or more ceramic layers that alternate with a metal electrode layer . The electrical behavior and, thus, the uses of ceramic materials are determined by their composition.
How many layers can a ceramic capacitor have?
The most common design of a ceramic capacitor is the multi layer construction where the capacitor elements are stacked as shown in Figure C2-70, so called MLCC (Multi Layer Ceramic Capacitor). The number of layers has to be limited for reasons of the manufacturing technique. The upper limit amounts at present to over 1000.
