Fixed Inductors

An inductor is a passive two-terminal electrical component that stores energy in a magnetic field when electric current is passed through it. It is used in circuits to introduce reactance to limit the flow of current in an inductive circuit, and as part of a filter to separate signals of different frequencies. A fixed inductor is an inductor with a fixed inductance rated at 1mH, 5mH, 10mH, etc. There are many types of fixed inductors available, such as air core, core-blocked, toroid and ferrite core.

SPM6550T-4R7M

The SPM6550T-4R7M is an example of a fixed inductor. It is a high-current power rated at 4.7mH with a mounting specification consisting of two screw terminals. This inductor provides reliable operation up to 500V and offers high power dissipation. It is also capable of carrying currents up to 25A.

Application Field and Working Principle

The SPM6550T-4R7M is mainly used in power supplies, switching converters, DC-DC converters, and motor drivers. It is also used in high-frequency impedance matching networks and inductive links. The magnetic field that is generated by this inductor is used to oppose the flow of alternating current (AC) in a circuit, thus preventing the current from reaching its maximum value.

In terms of the working principle, the inductor is a circuit that stores energy in a magnetic field when an alternating current is passed through it. This stored energy then resists changes in current as it is released. In other words, when an alternating current is passed through an inductor, the current flowing through it will be opposed, thus reducing its intensity.

The reason why inductors are used in a wide range of applications is their ability to store energy and resist changes in current. This makes them ideal for applications such as filtering out frequencies of a certain range, current sensing, and voltage regulation. They can also be used to reduce ripple noise in a circuit.

The SPM6550T-4R7M is a high-current power rated inductor that is used in a wide range of applications. It is easy to install due to its two screw terminals and offers reliable operation up to 500V. Furthermore, it is capable of carrying currents up to 25A and is ideal for applications such as power supplies, DC-DC converters, motor drivers, filtering, and current sensing.
