ELC-15E471L

Fixed Inductors are an important type of electrical components used to store electric energy in the form of a magnetic field and also to provide inductance in electrical circuits. The ELC-15E471L is a popular type of fixed inductor that is commonly used in various industrial and commercial applications. In this article, we will discuss its application field and working principle.

The ELC-15E471L is a common-mode chip inductor with high self-resonance frequency and low DCR. This component features an inductance of 15µH, a DCR of 0.047 mΩ (typical value), and a self-resonance frequency of 24MHz (typical value). It is available in various packages such as SOT-23 and SOT-223. This component is suitable for use in EMI/EMC applications such as low-noise and motor control, as well as power line filters.

The working principle of the ELC-15E471L is based on Faraday\'s law of induction. This law states that when a magnetic field is created around a conductor due to an applied voltage or current, an electromotive force (emf) or voltage is induced. In a fixed inductor like the ELC-15E471L, this induction is called the self-induction of the inductor. The voltage induced within the inductor opposes any change in the current that passes through it. This results in the current being limited, thus providing the required inductance.

In addition to being used in various EMI/EMC applications, the ELC-15E471L is also suitable for use in power line filters, RF antenna systems, switched mode power supplies (SMPS), and more. This component can also be used for noise suppression, power factor correction, and voltage reduction in logical circuits.

In conclusion, the ELC-15E471L is a popular type of fixed inductor that is commonly used in various industrial and commercial applications. This component works on the principle of self-induction and can be used for a number of purposes such as EMI/EMC applications, power line filters, RF antenna systems, SMPS, and more. We hope that this article has provided you with an understanding of the application field and working principle of the ELC-15E471L.
