Fixed Inductors

The SH50C-0.64-470 is an example of a fixed inductor, which is an electrical component that stores energy in the form of a magnetic field when current flowing through it. Fixed inductors can be classified based on the type of core they use, how the winding is configured, and their application. These components are widely used in a variety of applications, from power supplies to high-frequency antenna filters.

Application Field

In terms of application fields, fixed inductors are used in diverse areas. They are essential components for AC/DC power conversion, used in power supplies, circuits for controlling motors, switching power supplies, lightweight shared power supplies, and interoperability power supplies. Apart from these applications, fixed inductors are also used in communications equipment such as antenna filters, decoupling filters, and high-frequency circuit matching elements. Fixed inductors also find uses in automotive circuits, electro-acoustic circuit matching, and in various other fields of electronics.

Working Principle

The working principle of fixed inductors is based on Lenz’s Law and Faraday’s Law of Induction. Lenz’s Law states that an induced electromotive force (emf) in any closed circuit is always in such a direction that it opposes the source of utilization of the electrical energy. Faraday’s Law of Induction states that an emf induced in a circuit by a changing magnetic field is equal to the rate of change of the field through the circuit. Thus, when current flowing through a coil of wire creates a magnetic field, that field creates a force against the current in the opposite direction.

Additionally, fixed inductors are also characterized by reactance, which is the amount of opposition that a component or circuit exhibits to alternating current. Reactance is dependent on the frequency and inductance of the inductor. Low reactance components are used in power supplies to ensure no-load efficiency and higher efficiency at peak loads. Moreover, fixed inductors are also used to filter out any unwanted high frequencies.

Pros and Cons

Fixed inductors generally offer many benefits including good power handling, low antiresonance frequency, and high quality factor. They are ideal components in applications that require low-profile solutions and can have higher tolerances for ripple current. Furthermore, fixed inductors are also relatively cheap and available in a variety of sizes and shapes.

On the other hand, fixed inductors also have some disadvantages. Getting the best performance out of a fixed inductor requires careful consideration of various factors, such as careful selection of the core and winding material, the inductance value, the core material, and construction details. Moreover, fixed inductors are generally poor in filtering out high-frequency noise, which makes them unsuitable for use in high-frequency applications.

Conclusion

In conclusion, fixed inductors are important components used in many applications. The SH50C-0.64-470 is an example of a fixed inductor, which is an electrical component that stores energy in the form of a magnetic field when current flowing through it. Fixed inductors can be used in diverse areas such as power supplies, circuits for controlling motors, switching power supplies, lightweight shared power supplies, and interoperability power supplies, as well as for filtering out any unwanted high frequencies. They generally offer benefits such as good power handling, low antiresonance frequency, and high quality factor. However, they can also be relatively difficult to select and relatively inefficient in filtering out high-frequency noise.
