Fixed Inductors are types of passive electric components used to store energy in an electric field, usually composed of a coil of wire wound around a core. They have many applications in electronic devices, such as amplifiers, regulators and filters. One of the most popular fixed inductors is the ELC-09D561F. This component is designed for a wide range of applications, from switching power supplies to RF circuits.

The ELC-09D561F is a shielded power inductor, measuring 22.6mm by 9.2mm with a height of 5.2mm. It has a 5.5mm through hole mounting with heatsink for high power transmission. The device is typically available in three inductance values: 24mH, 15mH and 5mH. It also features a very low DC resistance and good performance in high-frequency switching applications. The inductor can operate between temperatures of -40°C to +85°C.

As for the working principle of the ELC-09D561F, it can be said that it functions as an inductor because it stores energy in its self-inductance. That is, it stores energy in an electric field that is generated by a current flowing through the coil. When current passes through the coil, it creates an electric field, which is responsible for inducing an opposite current in surrounding coils, thus creating a self-induced current that circulates around the inductor. Subsequently, this current has a varying amount of magnetic flux which is responsible for storing energy in the electric field.

The power inductor also has an inductance value and impedance curve, and it functions as a low-pass filter. This means it blocks high-frequency signals but allows low-frequency signals to pass. This is beneficial in certain applications that require power filtering, such as TV receivers or amplifiers. Moreover, it can be used for suppressing switching noise and harmonic in electrical motors.

In sum, the ELC-09D561F is a popular shielded power inductor which is designed for a wide range of applications, including switching power supplies, RF circuits and low-pass filters. With its low DC resistance and good performance in high-frequency switching applications, the device is suitable for low voltage, high frequency applications. Furthermore, its ability to block high-frequency signals while allowing low-frequency signals to pass makes it ideal for certain power filtering applications.
