Ceramic capacitors are a type of capacitor that uses ceramic as its dielectric material. They are widely used in electronic devices due to their stability, reliability, and cost-effectiveness. A key characteristic of ceramic capacitors is their ability to maintain a consistent capacitance value over a range of temperatures. This makes them suitable for use in applications where temperature fluctuations can affect the performance of the device. Additionally, ceramic capacitors are often used in high-frequency circuits due to their low loss characteristics.
