Fixed inductors are electromagnetic components that are used in many electrical and electronic applications such as power supplies, radio and television, and audio systems. The SLF7045T-221MR40-H fixed inductor is a popular choice for use in applications requiring high performance. Its features make it an ideal choice for applications ranging from high-current, low-voltage DC switching power supply applications to low-current, high-voltage AC applications.

The SLF7045T-221MR40-H is a surface-mount fixed inductor designed for use with low-voltage DC circuits. It is constructed from SLF (soft-magnetic steel) material. The core of the inductor is annealed in order to achieve maximum saturation and reduce the overall power consumption of the application. The inductor has a very small form factor, making it suitable for high-density circuit board design.

The SLF7045T-221MR40-H has a rated inductance of 2.2mH. It also features a tight self-resonance frequency up to MHz, an ultra-low DC resistance of 0.2 Ohm, and a current rating of up to 4.2A. These features make the inductor highly efficient and allow designers to achieve higher switching frequencies with fewer components.

The working principle of the SLF7045T-221MR40-H fixed inductor is based on the property of inductance, which is the ability of an inductor to store and release energy. When current passes through the inductor, a magnetic field is created that induces an EMF (Electromotive Force) in the inductor. This EMF opposes the change in current flow and as a result, the inductor acts as an opposition to changes in small current. As the current in the inductor increases, the magnetic field increases and the inductance increases as well. This helps to limit the current flow and provides the voltage drop that is necessary to regulate the current in the application.

The SLF7045T-221MR40-H fixed inductor is an ideal choice for use in high-performance applications. Its features allows for high-frequency switching and high-density circuit board design. It’s ability to efficiently store and release energy helps to reduce the power consumption of the application and is a great choice for applications that require low-voltage power supplies.
