Fixed Inductors

Inductors are one of the fundamental building blocks used in all electrical and electronic circuits. An inductor is a component that stores energy in a magnetic field when electric current flows through it. Inductors come in several varieties, such as fixed inductors, variable inductors, and adjustable inductors. Fixed inductors are devices that are designed to provide a specific inductance value for a specific electrical purpose. One such example is the ELC-18E5R6.

Application Field

ELC-18E5R6 is a small two-wire ferrite core inductor mainly used in the high-frequency analog circuits of electronic products like TV and audio equipment. Characteristic impedance of this device is 19 ohms, and it can handle continuous current of 0.6A and maximum input power of 7.2 W. This component is also suitable for the low ripple noise filtering in the DC-DC converters. Under certain conditions, it can also be used in the pulse applications of communications, mobile phone power management, and mobile charging. Compared to the ordinary inductors, this device has the advantages of small size and low insertion loss, which makes it a perfect choice for the high-density PCB design.

Working Principle

The working principle of a fixed inductor like ELC-18E5R6 is fairly simple. When electricity passes through the inductor, a magnetic field is generated that creates opposing forces on the electrons. This electromagnetic force is measured in Henries and is responsible for the electromagnetic energy storage that the inductor provides. The ELC-18E5R6’s ferrite core design allows for greater efficiency in generating and storing a magnetic field.Since an inductor provides its effective impedance by opposing the changes in the current, it can be used to control the current flow in the circuit. In a simple circuit, the current flowing through the inductor will charge the capacitor and the inductor will prevent the current from changing too quickly. It is this basic operation of inductors that makes them useful in signal conditioning, noise filtering, oscillator circuits, and other radio-frequency applications.

Conclusion

The ELC-18E5R6 is a small two-wire ferrite core inductor mainly used in the high-frequency analog circuits of electronic products. This component is suitable for applications such as low ripple noise filtering, communications, power management, and mobile charging. The working principle of the device is based on the generation and storage of electromagnetic energy in a ferrite core, which helps control the current flow in the circuit.
