Fixed Inductors

An inductor, also known as an el-coil or coil is a passive two-terminal electrical component which resists changes in electric current passing through it. It consists of a length of insulated wire, usually wrapped in a coil around a metallic core and forms a magnetic field when an electric current passes through it. Inductors are used in a wide variety of applications, ranging from consumer electronics to industrial systems. One such example is the SRP1040-1R7M, which is a fixed inductor from the SRP series by TDK.

SRP1040-1R7M Application Field

The SRP1040-1R7M is a low-profile, surface-mountable fixed inductor. It is ideally suited for use in space-constrained applications, such as mobile phones and game consoles. It is also suitable for other electronic devices with low-profile circuitry, such as digital video camcorders. Due to its low-profile nature, it can also be used in other consumer electronics, such as PCs and DVD players.

SRP1040-1R7M Working Principle

The SRP1040-1R7M is a fixed inductor consisting of a winded coil. It works by storing electrical energy in the form of a magnetic field. This occurs when an electric current flows through the inductor. The amount of energy stored is proportional to the inductance of the inductor, which is a property of the coil itself. As the current flow increases, the field strength increases, and so does the amount of energy stored in the inductor.

When the current flow is stopped, the energy stored in the inductor is released in the form of an electromotive force, known as ‘back electromotive force’. This force can cause current to flow back through the circuit in which the inductor is located. This back-flow of current is usually undesirable, as it can cause interference in the circuit or damage to other components. The SRP1040-1R7M limits this current back-flow, enabling its use in noise-sensitive applications.

Conclusion

The SRP1040-1R7M is a fixed inductor from the SRP series by TDK. It has a low-profile design, making it ideal for space-constrained applications. It works by storing electrical energy in the form of a magnetic field, and releasing it in the form of an electromotive force when the current flow is stopped. The SRP1040-1R7M also limits any current back-flow, enabling its use in noise-sensitive applications.
