.SLF7045T-3R3M2R2-H Fixed InductorsFixed inductors, also called fixed-frequency inductors, are electrical components that store energy and control electric and magnetic fields. Fixed inductors are divided into two types according to their application fields: magnetic-based inductors and non-magnetic based inductors. This article will focus on the application field and working principle of SLF7045T-3R3M2R2-H, a mica-based fixed inductor for low frequency use.Mica-based fixed inductors, such as SLF7045T-3R3M2R2-H, are constructed with a plastic housing or composite material, such as epoxy resin, filled with mica and wound with cores of magnet materials, such as aluminum or copper, located around the plastic housing. The core is usually composed of either a single loop of wire, several layers of coils, or a combination of both. The mica\'s small mass and excellent heat dissipation characteristics make it ideal for use in these types of inductors.SLF7045T-3R3M2R2-H fixed inductors are designed for use in low frequency applications, particularly those that require power conservation. For instance, they may be used in power line regulation solutions, which require precision control of power and voltage levels and steady current supply. SLF7045T-3R3M2R2-H fixed inductors also offer low signal distortion, high efficiency, low operating temperature, and low EMI generation.The working principle of the SLF7045T-3R3M2R2-H fixed inductor is based on Faraday\'s law of induction, according to which an electric current creates a magnetic field, and a changing magnetic field creates an electric current. In the SLF7045T-3R3M2R2-H fixed inductor, when an alternating current is applied to the inductor\'s core—the loop of metal wire—the electric field generated by the alternating current causes the metal\'s magnetic field to fluctuate in tandem. As a result, an electric current is generated in the opposite direction of the incoming alternating current, and this current is generated with an opposition to the flow of the incoming current. This opposition is known as impedance.The SLF7045T-3R3M2R2-H is an economical fixed inductor solution that offers reliable performance for DC-to-DC converters, inverters, batteries, and other low-frequency applications. Its construction of a mica-filled core with low mass ensures efficient performance, high signal-to-noise radiation, and low EMI. Its excellent heat dissipation characteristics make it ideal for power conservation solutions and low frequency applications that require reliable performance.
