Ceramic capacitors are a type of capacitor that uses ceramic materials as its dielectric. This category is one of the most common types of capacitors used in electronic circuits due to their cost-effectiveness, high reliability, and versatility. They are available in both fixed and variable capacitance versions. In addition to their widespread use in electronics, ceramic capacitors have various applications, including filtering, coupling, bypassing, and tuning. Their ability to withstand extreme temperatures, vibrations, and other environmental factors also makes them suitable for harsh environments. The primary components of a ceramic capacitor include two metal electrodes separated by a thin layer of ceramic material. The type of ceramic used can affect the capacitor's characteristics, such as capacitance value, temperature coefficient, and dissipation factor. Ceramic capacitors have evolved significantly over time, with advancements in materials science leading to improvements in their performance and reliability. They are now used in an array of industries, including aerospace, automotive, consumer electronics, and medical devices. Some common types of ceramic capacitors include: Ceramic disc capacitors Ceramic chip capacitors Axial leaded capacitors
