Ceramic capacitors are a type of capacitor used in electronics to store electrical energy, known as capacitance. They have several benefits and applications due to their characteristics and properties. The main advantage of ceramic capacitors is their ability to filter out unwanted frequencies while allowing desired signals to pass through. This property makes them useful in various electronic circuits for power supply filtering, decoupling, and noise reduction. Additionally, they are relatively inexpensive compared to other types of capacitors, making them a popular choice for many applications.
