1. Introduction to Fixed Inductors

A fixed inductor is a type of inductor that has a fixed inductance value, meaning its resistance to electric current doesn’t change over time or with the addition of components. This type of inductor is used primarily in electrical circuits to provide the necessary stable and reliable power.Fixed inductors are commonly seen in power supplies, voltage regulators, and other electronic components such as transistors and capacitors. They are used to help regulate the current in a circuit by providing a certain amount of resistance or capacitance depending on the application. The most common type of fixed inductors is the ferrite inductor, which is a type of permanent magnet made from ferrite powder. Other types of fixed inductors include metal oxide, ceramic, and film capacitors.

2. 1008R-220K Application Field and Working Principle

The 1008R-220K is a type of fixed inductor designed for high frequency applications. It has a resistance value of 220K ohms and can handle frequencies up to 30MHz. The 1008R-220K is used primarily in electronic circuits that involve high frequency signals, such as those found in television receivers, radios, and computers.The basic working principle of the 1008R-220K is the same as for any other inductor: when an alternating current (AC) is applied to the inductor, the changing electrical current produces a changing magnetic field which stores energy. This stored energy is then available for use in the circuit. As the current changes, so does the resistance of the inductor. The 1008R-220K is designed to be highly efficient, meaning it is able to provide a high amount of output current with a relatively low amount of input voltage. This makes it ideal for applications that require a lot of current without the need for a large voltage source. Its high inductive reactance also makes it useful for filtering, as it can reject signals of certain frequencies while allowing others to pass through.

3. Conclusion

The 1008R-220K is an extremely useful and versatile type of fixed inductor. Its high efficiency, high inductive reactance, and ability to handle frequencies up to 30MHz make it ideal for applications such as television receivers, radios, and computer circuits. It is also useful for filtering, as it can filter out signals of certain frequencies while allowing others to pass through. With its wide range of applications, the 1008R-220K is a valuable component for any electronic circuit.
