Fixed inductors are components that store electrical energy in an inductor coil when an electric current passes through it. The ELJ-LA470KF is a type of fixed inductor that is designed to work as an output choke filter for mobile phones. This product is ideal for use in high-frequency applications and has an inductance of 4.7µH.

The ELJ-LA470KF is a surface-mount inductor, made by combining a magnetic body and an external inductance coil. This makes it possible to achieve higher surface densities on circuit boards, while also improving noise suppression. The inductor also features high-temperature bonding material that can withstand temperatures of up to 300°C, making it suitable for use in high-temperature applications.

The working principle of the ELJ-LA470KF inductor is relatively simple. It has two pins: one is the inductor ground pin, and the other is the inductor pin. When an alternating current is applied between the two pins, it causes a magnetic field to be produced in the coil. This magnetic field then induces an electric current in the inductor and the resulting voltage drop across the inductor reduces the amplitude of the applied current.

The ELJ-LA470KF is designed to be used in high-frequency applications, such as in mobile phones. The inductor helps reduce noise in these applications by acting as a choke filter. It does this by blocking high-frequency signals while still allowing low-frequency signals to pass through. This reduces the amount of unwanted noise from the signal.

The high-temperature bonding material used in the construction of the ELJ-LA470KF also makes it suitable for use in high-temperature applications. The inductor can withstand temperatures of up to 300°C which makes it ideal for use in automobiles, industrial equipment, and other applications where high temperatures may be encountered.

In summary, the ELJ-LA470KF is a type of fixed inductor that is designed to work as an output choke filter for high-frequency applications, such as mobile phones. It uses a magnetic body and external coil to achieve higher surface densities, while also providing noise suppression. The high-temperature bonding material makes it suitable for use in high-temperature applications, such as automobiles and industrial equipment. Its working principle is relatively simple; an alternating current is applied between two pins, producing a magnetic field that induces an electric current in the inductor and reduces the amplitude of the applied current.
