Fixed Inductors

Fixed inductors, or also known as chokes, are passive electrical components used to store energy in the form of magnetic fields. They are commonly used to block direct current, while allowing a certain signal or frequency to pass. One popular type of fixed inductor is the 4307-475J, which is widely used both in commercial products and in commercial and industrial applications.

Application Field

The 4307-475J fixed inductor is primarily used for switch-mode power applications, as they can operate up to a frequency of 1 MHz. It is used to filter out noise and control the power delivery of DC-DC switching power supplies. Additionally, the 4307-475J also has low power loss, making it suitable for high-efficiency, high-frequency applications. Furthermore, it is also useful as a voltage-dropper, which is important for a variety of LED display and lighting products.

Working Principle

Fixed inductors, such as the 4307-475J, use an inductor or coil of wire that creates a magnetic field when electricity passes through it. This magnetic field, in turn, induces a voltage in the coil and creates a current. This effect is called inductance, and it is the basic principle upon which the 4307-475J operates. When a voltage is applied across the coil, the inductor stores the energy from the voltage in the form of a magnetic field. This energy is then released as a current when the voltage is removed.

The 4307-475J uses a ferrite-core with a single-wire winding to further enhance performance. This design ensures that the inductor can achieve a wide range of frequencies while continuously dissipating energy. Additionally, the 4307-475J also has a temperature range of -40°C to +125°C, which makes it suitable for automotive applications, as well.

Conclusion

In conclusion, the 4307-475J fixed inductor is a versatile component that is suitable for a wide range of applications. It can operate at a wide range of frequencies and has a temperature range that is suitable for even the harshest environments. Additionally, its ferrite-core design ensures high performance and reduced power loss. Therefore, it is an ideal choice for many DC-DC switch-mode power applications, as well as for voltage drop and noise-filtering applications.
