Ceramic capacitors are a type of capacitor made from ceramic materials. They are commonly used in electronic circuits due to their stable capacitance values over a wide range of temperatures. One advantage of ceramic capacitors is that they are relatively inexpensive compared to other types of capacitors, making them suitable for applications where cost is a concern. Additionally, they have low leakage current and high insulation resistance, which helps prevent electrical noise and ensures reliable operation in many electronic devices.
