With the development of technology, mobile phones, tablets, and computers have become essential tools in our daily life and work. People’s requirements for these electronic products’ performance and functionality are increasingly higher, while also expecting smaller sizes for better portability, which places greater demands on electronic components.
Ceramic capacitors are capacitors that use high dielectric constant ceramic materials as the medium. They are made by applying metal films (usually silver) onto ceramics and forming electrodes through high-temperature sintering. These capacitors feature small size, large capacitance, good frequency characteristics, and high stability, making them widely used in electronic products.
In computer circuits, ceramic capacitors serve three important functions:
Filtering Function
Computer power circuits generate numerous high-frequency interference signals that can affect the normal operation of computer components. Ceramic capacitors respond quickly to high-frequency signals and have low loss, effectively absorbing and isolating these interferences to ensure stable and clean power supply to all computer components.
Coupling Function
In computer signal transmission circuits, ceramic capacitors help transfer signals from one circuit to another. This signal transmission is particularly important for complete and accurate transmission of information such as audio and video, ensuring we can see clear images and hear clear sounds.
Voltage Stabilization
When computer loads change or power fluctuates, voltage becomes unstable. Ceramic capacitors can store and release electrical energy, smoothing the power supply voltage and preventing voltage fluctuations from affecting other circuits, ensuring stable computer operation.
In conclusion, as one of the fundamental electronic components in computers, ceramic capacitors play an irreplaceable role in ensuring normal, stable, and efficient computer operation.
