Fixed Inductors: AIML-1206-1R0K-T Application Field and Working Principle

Fixed inductors are an important element in many electrical circuits. In the electronic industry, fixed inductors, such as the AIML-1206-1R0K-T, are widely used in a variety of applications. This article will discuss the application field of this particular type of inductance as well as its working principle.

AIML-1206-1R0K-T Characteristics

The AIML-1206-1R0K-T is a surface-mount, automotive-grade inductor with a tolerance of 10%. It is rated for 11.5A with a dc resistance of 0.3Ω. It features an operating temperature range from -55°C to +150°C. The unit is constructed from a soft ferrite core with a sputtered nickel covering. The inductance of the AIML-1206-1R0K-T ranges from 0.006µH up to 10.5µH.

Application Field

Fixed inductors are used in various circuit topologies, such as power supplies and low-noise amplifiers. The AIML-1206-1R0K-T inductor is primarily used for low-noise communications systems, EMI/RFI filters, and for power distribution in the automotive and aerospace industries. The low dc resistance and high saturation current makes it highly suitable for applications in which long-term reliability and high efficiency are required.

Working Principle

Inductors are passive components that work on the principle of inductance. Inductance is a property of an electric circuit by which an electromotive force is generated in the circuit whenever the current changes. This phenomenon is known as Lenz\'s Law. The electrical energy stored within the inductor is converted into magnetic energy. This energy is then stored in the form of a magnetic field. An inductor has a direct relationship between the current and the magnetic flux it produces, known as the inductance of the circuit.

When a current passes through an inductor, it induces an opposing electromotive force (EMF) in the inductor. This is known as back-EMF and is produced by the change in current. This EMF is proportionate to the rate of change of current in the circuit. The EMF opposes the applied current and therefore reduces the magnitude of the current across the inductor. This is known as inductive reactance, and is measured in ohms.

The magnitude of an inductor\'s inductance is determined by the quality of its core material (ferrite or iron), the number of turns, and the physical size of the inductor. The larger the inductor, the more energy it can store, and the higher its inductance. The AIML-1206-1R0K-T has a sputtered nickel covering that provides extra shielding from external electromagnetic interference. This helps to reduce noise and improve inductor performance.

Conclusion

The AIML-1206-1R0K-T is an excellent choice for automotive and aerospace applications because of its low dc resistance and high saturation current. It has a wide operating temperature range and is constructed from a soft ferrite core with a sputtered nickel covering. The inductance of this fixed inductor ranges from 0.006µH up to 10.5µH. It works on the principle of inductance, in which an oppositional force is generated in the circuit whenever the current changes, resulting in a reduction in the magnitude of the current across the inductor.
