Fixed inductors are an essential electronic component used in a variety of electrical and electronic devices. The SPM4012T-2R2M-LR is a type of fixed inductor that can be used in a broad range of applications. In this article, we’ll discuss the application field and working principle of the SPM4012T-2R2M-LR.

The SPM4012T-2R2M-LR is a fixed inductor with an inductance of 2.2µH. It has a current rated at 2A and a winding resistance of 0.014Ohms. This fixed inductor is designed to operate with currents up to 10A and has a self-resonant frequency of up to 8 MHz. It is also designed to operate in temperatures up to 130°C without core saturation.

The SPM4012T-2R2M-LR is a widely used inductor as it is suitable for applications in power conversion circuits such as DC/DC converters, inverters, AC/DC power supplies, and power line filters. It’s also suitable for RF or IF signal filtering and noise suppression in communication systems, automotive, and medical devices. Additionally, it can be used in low-voltage DC/DC applications, battery circuits, and other electronic circuits where an inductor is needed.

The SPM4012T-2R2M-LR works using the same basic principle as any other inductor. When a current passes through the inductor, a varying magnetic field is created. This creates an opposition to the change in current with the rate at which the magnetic field is changing. This opposition is known as inductance, which makes the SPM4012T-2R2M-LR an ideal choice for applications requiring high-current handling and noise suppression.

The SPM4012T-2R2M-LR is also a popular choice in industrial applications due to its low leakage and low EMI characteristics, as well as its high efficiency. Its robust design ensures that it can work reliably even in the harshest environments, making it suitable for a wide variety of industrial applications.

In summary, the SPM4012T-2R2M-LR is a fixed inductor designed for applications in power conversion circuits, RF and IF signal filtering, and low-voltage DC/DC applications. It has a rated current of 2A and a self-resonant frequency of up to 8 MHz. It is designed to operate with currents up to 10A and in temperatures up to 130°C without core saturation. The device works using the same principle as any other inductor, creating a varying magnetic field that opposes changes in current, resulting in a high current handling and noise suppression.
