Fixed inductors are widely used in the electronics industry to store and deliver energy in a range of applications. The SLF7045T-221MR33-PF inductor is designed to offer reliability, flexibility, and robustness for wide range of industrial, automotive, and consumer applications. The SLF7045T-221MR33-PF is a common-mode communication filter inductor which is designed for high efficiency and moderate power applications.

The SLF7045T-221MR33-PF has a maximum DC resistance of 0.35Ω and operates over a temperature range of -40°C to +85°C. It is designed for minimal voltage loss due to ESR, with an operating frequency range of 100kHz to 1MHz maximum. The inductance is on the order of 220uH ±20%. It has a ferrite core material that allows for successful distribution of the magnetic field in order to provide reliable inductance performance.

The inductor is designed using a molding process which creates the thin conductive windings on the core. This allows for increased protection from physical damage due to increased thermal endurance. The inductor can disperse heat effectively due to its high maximum temperature and high thermal dissipation ratio, due to its low thermal impedance.

The inductor provides excellent common mode filtering performance for high-speed data communication lines. Its small inductance size allows it to take up very little space on a circuit board which helps designers reduce the overall size of the system. This is advantageous for embedded applications where board space is limited.

In application, SLF7045T-221MR33-PF can be used in circuits such as radiation tolerant high-speed communication lines, DC-DC converters, motor controllers, high-speed power supply, and AC-DC converters. It is perfect for use in automotive, railways, consumer electronics and industrial systems.

The working principle of the SLF7045T-221MR33-PF fixed inductor is based on the fundamental principles of electromagnetic induction. If an electrical current is flowing through a wire, a magnetic field is generated around the wire. This magnetic field exerts a force on other nearby wires, especially by inducing an electrical current. The induced current is proportional to the rate of change of the magnetic field, which is directly proportional to the rate of change of the electrical current flowing. The induced current in the wire is then opposed to the current that created the magnetic field, resulting in a decrease in the total energy in the system called inductive resistance, since the energy of the entire system is conserved.

The SLF7045T-221MR33-PF fixed inductor is an efficient and reliable part that is designed for a wide range of industrial, automotive, and consumer applications. Its small footprint is advantageous for embedded applications with space limitations, and due to its low DC resistance, offers reliable performance and low power losses. The optimization of its electrical characteristics offers an optimal balance between power consumption, applicability, and cost. The working principle of the inductor is based on the fundamental principles of electromagnetic induction, which produces inductive resistance when an electrical current is flowing through a wire and creating a magnetic field.
