Fixed Inductors

Inductors are electrical components that store energy in a magnetic field. They are defined as two or more closely coupled coils that generate a magnetic field when an electric current passes through them. The most common type of inductor is the wound-wire coil, also known as a fixed inductor, but other varieties exist. Fixed inductors are primarily used to act as filters, blocking high-frequency signals while allowing low-frequency signals to pass through. They are also used to regulate and maintain current flow in an electrical circuit.

The NRS4012T4R7MDGJ is an example of a fixed inductor. It is a surface mount device designed for power applications, such as mobile phone chargers and electric car charging stations. This device provides outstanding current and voltage handling capability in a small package. It has a low profile height and an excellent heat dissipation. It can handle up to 4.7 millihenries and has a highly stable magnetic core.

Application Field

The NRS4012T4R7MDGJ fixed inductor is designed for power applications, and is suitable for installation in areas with limited space. It is also suitable for mobile phone chargers, electric car charging stations, and other applications that require stable current and voltage performance. Its excellent heat dissipation capability ensures that it stays within its operating limits even with heavy use. Additionally, its low profile allows for easier installation when space is limited. It is also designed for EMF suppressing applications, such as lighting circuits and power transformers.

Working Principle

The NRS4012T4R7MDGJ fixed inductor works by creating a magnetic field when a current passes through it. This field then induces a voltage in the secondary winding, which produces a current in the secondary circuit. This current is then used to regulate the voltage and current in the main circuit. The device also works to filter out high-frequency signals, while allowing low-frequency signals to pass through. This is done by temporarily storing electrical energy in the magnetic field it creates, then releasing it in short bursts and regulating the amount of current that is released.

Conclusion

The NRS4012T4R7MDGJ fixed inductor is a small and highly efficient electrical device designed for power applications. It has a low profile and excellent heat dissipation capabilities. It can also suppress EMF in lighting circuits and power transformers. This device works by creating a magnetic field when a current passes through it, which then induces a voltage in the secondary winding. This current is then regulated by the device to both filter out high-frequency signals and regulate the current and voltage in the main circuit.
