A ceramic capacitor is a type of capacitor that utilizes ceramic as the dielectric material. The ceramic dielectric allows for high capacitance values within a compact size, making these capacitors ideal for space-limited applications. Ceramic capacitors come in various shapes and sizes, providing versatility for a range of applications.
These capacitors are commonly used in low-frequency applications and basic electronic circuits. A multilayer ceramic capacitor consists of multiple layers of ceramic material interleaved with metal electrodes. This construction allows MLCCs to achieve high capacitance values within a small footprint.
Even when used within the capacitor's maximum operating temperature, these capacitors may require a reduced voltage to maintain reliability. However, KEMET ceramic capacitors are designed and qualified to operate at full-rated temperature and voltage.
C 2.9.1 Construction The capacitors consist, as the name tells us, of some kind of ceramic. The manufacturing process starts with a finely grounded ceramic powder mixed to an emulsion of solvents and resin binders.
Disc ceramic capacitors have a simple, disc-shaped design. They consist of a ceramic disc with electrodes on either side. These capacitors are commonly used in low-frequency applications and basic electronic circuits. A multilayer ceramic capacitor consists of multiple layers of ceramic material interleaved with metal electrodes.
Class III ceramic capacitors, like Z5U, offer high capacitance but struggle with temperature stability. The diversity in the characteristics of these capacitors makes them a suitable choice for a variety of applications, establishing them as the most used capacitors in today’s circuits.
