Fixed Inductors

An inductor is an electrical component used in electronics circuits to limit the current flow, creating a “back-emf” to counter the flow in the circuit. Fixed inductors are inductors with a fixed value of inductance – for example, the ELL-SFG100MA inductor. It is an SMT power inductor with a low DCR, high inductance and low resistance, and can be used in a variety of applications.

Features

The ELL-SFG100MA is a planar, toroidal SMT power inductor with a high saturation current, low resistance and a high inductance. It is radial termination and is suitable for high power applications such as switching regulators, converters, DC-DC converters and other power management applications.

Applications

The ELL-SFG100MA inductor can be used in a variety of applications, including power converters, switching regulators, DC-DC converters, power management applications in automotive, consumer electronics, and telecommunications, as well as LED lighting and smart home applications.

Working Principle

The principle of operation for this type of inductor is relatively simple. When current is applied through the inductor, a magnetic field is generated which opposes the current, thus limiting the current flow. The inductor has an inductance which is proportional to the voltage applied, and this causes the current flow to be reduced by the amount of voltage applied. This is known as back-emf.In addition, the inductance of the inductor also has an effect on the amount of current that can flow through the inductor. The higher the inductance, the lower the current that can flow. This feature is useful in applications such as DC-DC converters, where high frequencies are necessary for efficient control of the power supply.

Conclusion

The ELL-SFG100MA is a fixed inductor that can be used in a variety of applications due to its features, such as high saturation current, low resistance, and high inductance. Its working principle is relatively simple, with the magnetic field generated by the current flow through the inductor working to limit the current, as the inductance is proportional to the voltage applied. This inductor is a great choice for power converters, switching regulators, DC-DC converters, and other power management applications.
