Fixed Inductors

An inductor, also known as a coil, choke, or reactor, is an electronic component that stores or resists energy in a magnetic field. Fixed inductors, like the SLF6025T-220MR73-PF, are devices with a static or constant inductance value. They store and regulate electrical current in a circuit.

Application Field:

Fixed inductors like the SLF6025T-220MR73-PF used in a wide range of applications. They are primarily used to filter electrical power signals, prevent spikes and reduce electrical noise in audio and video systems. Furthermore, they play an important role in the circuits of computers, mobile phones, entertainment devices, and other electronic consumer goods.

Working Principle:

The working principle of the SLF6025T-220MR73-PF operates on the concept of Faraday’s Law of Induction. This rule states that an electromotive force (EMF) is induced in an electric conductor when it is exposed to a changing magnetic field or the field moves relative to the conductor. Essentially, the device works by using the magnetic field to generate an electric current. The current is generated by energizing one of the two wires. This generates a changing magnetic field which induces a current in the second wire.

The SLF6025T-220MR73-PF fixed inductor has an internal iron core which increases the inductance of the device. An enlarged core size improves the inductance of the device as the number of turns is increased. As more current flows through the device, more magnetic field lines are produced, thus increased voltage is induced in the secondary winding of the device.

The SLF6025T-220MR73-PF also contains a Bobbin holder, which serves the purpose of holding the wire in the correct position to ensure maximum performance. The Bobbin holder also prevents the wire from moving or vibrating, further increasing the performance of the device. In addition, the Bobbin holder provides an electrical path that allows the magnetic field generated from the primary winding to induce a voltage in the secondary winding.

The inner core material of the SLF6025T-220MR73-PF is made of high quality ferrite which makes it an ideal choice for providing long term reliability and stability. The iron core increases the inductance of the device by concentrating the magnetic field lines. This increases the voltage induced in the secondary winding which, in turn, increases the amount of power converted from the primary winding to the secondary winding.

The SLF6025T-220MR73-PF is an extremely versatile device as it can be used to build several DC/DC converter topologies. It can be used to build constant current, constant voltage, and buck-boost type power supplies. Moreover, since the device has a low DC resistance, it is suitable for applications which require a low power dissipation.

In conclusion, the SLF6025T-220MR73-PF is an ideal fixed inductor for applications that require an increased inductance and increased voltage induced in the secondary winding. The device has a wide range of applications such as filtering electrical power signals, preventing spikes, and reducing electrical noise in audio and video systems, as well as in computers, mobile phones, and other electronic consumer goods.
