Fixed inductors store energy in the form of magnetic fields and can be used to create inductors with predetermined parameters. This makes them ideal for controlling voltage and current in circuits as well as coupling two circuits together. The ELC-12D271E is an example of a fixed inductor, and the following sections will discuss its application field, as well as its working principle.

Application Field

The ELC-12D271E is an 8088-compliant, surface mount, fixed inductor commonly used in telecom and computer applications, such as local area networks, cellular phones, and Wi-Fi systems. Additional applications include power supply and voltage regulation. This component can also be used to create audio or power filters for sound systems and other applications.

The ELC-12D271E is designed for use in circuits with high frequencies and is particularly well suited for use in circuits with fast rise times (tr) and fast fall times (tf). The ELC-12D271E is capable of supporting up to 10A peak current, making it useful for current limited applications. Its inductance value of 270nH ensures that it can be used to create high-Q filters for most circuit designs.

Working Principle

The ELC-12D271E is constructed using two wire-wound input coils, one for the input and one for the output. The input coil is made from a high-purity ferrite core material, while the output coil is constructed of a ceramic core material. A conductive shield, typically a layer of copper foil, is wound around the output coil. This shield helps to reduce noise and increase the inductor\'s efficiency.

The ELC-12D271E operates in a manner similar to other inductors. When an electric current is applied, a magnetic field is created within the inductor that stores energy. This energy is then released as the current decreases, allowing the inductor to maintain a consistent voltage. The effective inductance of the ELC-12D271E is determined by the number of turns and the size of the core material.

The ELC-12D271E also provides some level of voltage protection to its circuit. When the voltage exceeds its rating, the inductor will absorb a portion of the excess energy, thus protecting the components from damage. The effective frequency response of the ELC-12D271E is determined by its self-resonant frequency.

In conclusion, the ELC-12D271E is a surface mount, fixed inductor that is well suited for applications in the telecom and computer industries, as well as power supplies and audio filters. The device uses two wire-wound coils, with one made from ferrite and the other from ceramic, to store energy in the form of a magnetic field and to regulate voltage in the circuit. The ELC-12D271E provides some level of surge protection and has a self-resonant frequency. This makes it an ideal component for use in high-frequency applications.
