Fixed Inductors

Fixed inductors are electrical components useful for filtering, tuning, and coupling of electrical signals. They offer the benefit of having a low profile and being relatively easy to install compared to more complex components like transformers.

The ELJ-FC470KF is an example of a fixed inductor. It has a compact size and is relatively easy to use. This type of inductor is mainly used in impedance matching circuits for radio frequency (RF) signal conditioning.

Application field

The ELJ-FC470KF is primarily used in radio frequency applications, such as GPS receivers and satellite communications. This inductor is also used in automotive electronics applications, like radio receivers and amplifiers.

It is also used in medical equipment and robots, as well as automated test systems for measuring, testing, and controlling. The inductor works in both alternating current (AC) and direct current (DC) circuits, and can be used for converting the signal between the two.

Working principle

Fixed inductors use a core material, such as ferrite, copper, or aluminum tapes, that stores energy in its magnetic field. When a current passes through the inductor, the electric field induces a magnetic field, which creates an electromagnetic field.

This field then interacts with the core material and creates a counter electromotive force (EMF), also known as a voltage drop. This voltage drop is then used to filter or tune the signal before it continues on to its destination.

The voltage drop can be adjusted by changing the inductor\'s core material or by changing the size of the coils. This allows the designer to fine tune the inductor\'s properties for different applications.

The ELJ-FC470KF is a versatile fixed inductor that can be used in a variety of applications. Its smaller size allows for easier installation than more complex components, and its magnetic properties make it an ideal filter or tuning device.
