Ceramic capacitors are a type of capacitor that utilize ceramic materials in their construction, specifically in the dielectric layer. They are known as one of the most common types of capacitors used in electronic circuits due to their affordability and wide range of applications. Characteristics: - Low cost - High capacitance values available - Small size - Wide operating temperature range Types: - Class 1: Ceramic capacitors with X7R or Y5V dielectric materials, which exhibit high capacitance and low loss at temperatures up to +125°C. - Class 2: Ceramic capacitors using NPO (NP0) dielectric materials, offering stable capacitance over a wide temperature range but lower capacitance values compared to Class 1 types. - Class 3: Specialized ceramic capacitors with Z5U or U2J dielectric materials for high frequency applications and limited temperature range. Applications: - Filtering - Coupling - Decoupling
