Fixed-inductors are often used in electronic circuits where an exact inductance value is required. The ELL-SFG181MA is a fixed inductor designed for a wide range of applications, from low-frequency circuit protection to high-frequency switching devices. This device has low electrical and magnetic losses, which make it suitable for use in switching applications.

The ELL-SFG181MA is a ferrite-wound, fixed inductor with a rated inductance of 1.81 mH (millihenry) and a maximum current of 3 A (amperes). It has a printed circuit board with two solder pins that are used to connect the inductor to the host circuit. It also has a pair of terminal pins which enable it to be easily mounted onto the host circuit board. The inductor is internally protected against overvoltage and reverse polarity. It is also rated as UL1411-approved for use in hazardous locations.

The working principle of the ELL-SFG181MA is based on Faraday’s law of induction. This law states that when a current is passed through a copper coil, the motion of the electrons within the coil generates a magnetic field which, in turn, induces a current in an adjacent conductor. The ELL-SFG181MA is designed with two coils that are wound in series, with one coil winding in the same direction as the other. This creates an increased inductance, reducing the amount of current that can pass through the circuit.

The ELL-SFG181MA is a robust and reliable component that can be used in a variety of applications. It is mainly used in power supplies, motor drives, inverters, portable communication equipment, and other power-electronic systems. It is also used in automotive, telecommunications, aerospace, computers, and consumer electronics applications. The ELL-SFG181MA is an ideal choice for applications that require a fixed inductor with superior efficiency and performance.

In conclusion, the ELL-SFG181MA is a fixed inductor designed for a variety of applications requiring a reliable and high-performance component. It is based on Faraday’s law of induction, and it is constructed with two coils that are wound in series for increased inductance. The ELL-SFG181MA is well-suited for a wide range of applications, including those in power supplies, motor drives, inverters, portable communication equipment, automotive, telecommunications, aerospace, and consumer electronics.
