IR04BH470J

Fixed inductors are electronic components that store energy in the form of magnetic fields. IR04BH470J is a type of fixed inductor designed specifically for automotive applications with high current requirements. This article will provide an overview of the IR04BH470J\'s application field and working principle.

Application Field

The IR04BH470J is a high current automotive inductor with a 4.7uH inductance value. It has a rated current of 25 amps and a low DCR of 0.188 ohms. This inductor can be used in various automotive electronics, such as Electric Vehicle (EV) chargers, on-board chargers, fuel cells, power window regulators, and power steering, as well as other high-power applications.

The IR04BH470J is designed to reduce electrical noise caused by the current flow in typical automotive applications. Its magnetic field has a high permeability, which helps to reduce the magnetics load of these applications. The inductor also has excellent heat dissipation, which helps to keep the system temperature lower when long-term high current operations are required.

Working Principle

The working principle of the IR04BH470J is based on the principle of Faraday’s Law. This law states that a change in the magnetic flux through a wire loop results in an induced electromotive force, which in turn induces a current. This can be represented graphically in a function of time which is known as the rising flux curve. This curve shows the relationship between the induced voltage and the time period of the magnetic flux change.

The inductor is designed to operate in a specific frequency range. The frequency of the current and the rising flux of the applied magnetic field create a resonance within the coil, which in turn increases the applied magnetic field. This is what gives the inductor its high current capability. In order to ensure the highest current output possible, it is important that the inductor is placed in the optimal position and that the surrounding environment is free from any noise-causing elements.

Conclusion

The IR04BH470J is a high current automotive inductor designed specifically for electric vehicles and other automotive applications. Its 4.7uH inductance value is combined with a high permeability magnetic field and excellent heat dissipation to create a high current output. In addition, its working principle is based on Faraday’s Law, which states that a change in the magnetic flux through a wire loop results in an induced electromotive force.
