Fixed Capacitors

Fixed capacitors are electronic components that have a fixed capacitance value that cannot be changed. They are used in electronic circuits to provide a specific capacitance value for a given application.

Fixed capacitors are made using a variety of dielectric materials, including ceramic, tantalum, aluminum electrolytic, polyester, and polypropylene. The choice of dielectric material depends on the specific requirements of the application, such as operating voltage, temperature range, and stability.

Fixed capacitors are available in a variety of shapes and sizes, such as through-hole, surface mount, and leaded types. They can also be classified based on their operating voltage, tolerance, and temperature coefficient.

Some common applications of fixed capacitors include decoupling, filtering, timing, and coupling circuits. In decoupling circuits, fixed capacitors are used to filter out unwanted high-frequency noise and ensure stable power supply operation. In timing circuits, fixed capacitors are used to set the time constant and determine the frequency of oscillation.

One of the main advantages of fixed capacitors is their stable capacitance value, which does not change over time or with changes in operating conditions. This makes them suitable for applications that require consistent and predictable performance.
