Fixed inductors, as their name implies, are electrical components comprised of coils and cores with fixed inductance. Such devices are highly versatile and are widely used in various electrical applications, including filtering, signal processing, and power conversion. The S4924R-104K is one such fixed inductor. In this article, we will explore the application field and working principle of the S4924R-104K.

Application Field

The S4924R-104K is a small, shielded, high-current, low-profile inductor with a ferrite core. It is highly suitable for power conversion and noise/EMI suppression circuits, and is often used in converters, LCD power supplies, small motor drivers, and switched mode power supplies. The inductors are available in various toroidal and flat packages, as well as in radial and axial configurations, allowing for flexibility in design and construction. The S4924R-104K also has excellent heat dissipation performance. Its inductance is very stable over the entire temperature range, and it boasts a wide range of operating temperatures, from -40°C to +150°C.

Working Principle

The S4924R-104K relies on magnetic flux to perform its work. The device’s core consists of soft magnetic material such as iron, which helps it concentrate the magnetic field into a single loop or path, making it possible for the inductor to store energy in the form of magnetic flux. When the current flowing through the inductor is increased, the magnetic field increases, and as a result, the core material stores more energy in the form of magnetic flux. When the current is decreased, the stored energy is released in the form of induced voltage, allowing the device to operate in various power conversion and noise/EMI suppression circuits.

In addition to the ferrite core, the S4924R-104K also features a shielded, high-current winding wrapped around the core, which helps it reach higher levels of performance. The winding is constructed from an ultra-thin copper wire that gives the device the ability to handle higher currents without significant inductance loss. This makes it ideal for use in power converters and noise/EMI suppression circuits.

Conclusion

In conclusion, the S4924R-104K is a high-performance fixed inductor with excellent characteristics. It is suitable for power conversion and noise/EMI suppression applications, and its core and high-current winding provide superior stability, heat dissipation, and inductance loss. As such, the S4924R-104K is an ideal choice for a wide range of electronic applications.
