ELC-18B562L

Fixed inductors are electronic components that store energy in a magnetic field. In most cases, they are constructed as a cylindrical coil of insulated copper wire wound around a core of ferromagnetic material like iron or ferrite, with a specified number of turns. Depending on the application, they can be made with open or closed magnetic circuits. Though the ELC-18B562L would appear to be no different, its application field and working principle sets it apart.

The ELC-18B562L fixed inductor from TDK-Lambda America is designed for use in high current automotive applications. In order to cope with the large inrush currents often present in such applications, the ELC-18B562L utilizes a double-sided slug and a ferrite core with a double-gapped magnetic circuit. This helps reduce the generation of flux leakage and reduce heating in the inductor. The inductor also features a current rating of 18A and a highly reliable insulation system. As a result, the ELC-18B562L is well suited for use in audio and power amplifiers, and other applications that require high current.

The working principle behind the ELC-18B562L inductor is the same as in many other inductors. When an electrical current passes through the inductor, a magnetic field is created. The strength of this magnetic field is proportional to the current passing through the inductor. When the current is removed, the magnetic field slowly collapses. As it collapses, it induces a voltage into the inductor winding, which results in a current in the opposite direction. This current is known as the back EMF. The core material used in the ELC-18B562L is designed to increase the efficiency of the inductor and reduce the generation of heat.

The double-sided slug and ferrite core in the ELC-18B562L also allows it to withstand higher temperatures than other fixed inductors. This makes it a great choice for automotive applications which may be subjected to higher temperatures and high inrush currents. In addition, the double-gapped magnetic circuit helps to reduce the flux leakage and prevent disruption of other components in the system.

Overall, the ELC-18B562L fixed inductor from TDK-Lambda America offers an ideal solution for automotive applications which need to withstand the high inrush currents and temperatures of these applications. With its’ double-sided slug and ferrite core, along with its double-gapped magnetic circuit, the ELC-18B562L provides an efficient, reliable and cost-effective solution to automotive power and audio applications.
