Fixed inductors are electrical components that store energy in the form of a magnetic field. They are used as part of an electronic circuit to induce and store a current, and are commonly used in communications equipment, radio frequency applications, and medical electronic devices. The ELL-4FG4R7NA inductor is one such example of a fixed inductor.

The ELL-4FG4R7NA is a fixed inductor that is used for various radio frequency applications. It has a maximum inductance of 220 nH and can handle up to 25V DC. It has an operating temperature range of -40°C to +85°C and a storage temperature range of -55°C to +125°C. It is a low profile inductor, measuring in at just 1.6mm in both height and width. The ELL-4FG4R7NA also has an operating frequency range of 0 to 180 MHz, allowing it to be used in a variety of RF applications.

In terms of its use in radio frequency applications, the main function of the ELL-4FG4R7NA is to act as a filter or blocking capacitor to restrict the movement of high frequency signals. This is done by passing a DC current through the inductor, which then creates a magnetic field. This field then acts as a barrier, preventing high frequency signals from passing through. The ELL-4FG4R7NA inductor is also used as an amplifier, allowing the signal to be amplified without introducing any distortion due to its high frequency response.

The working principle of the ELL-4FG4R7NA is relatively simple. When a DC current is passed through an inductor, it creates a magnetic field. This field then causes a voltage to be induced across the inductor. This voltage is known as the \'back emf\', and its value is equal to the rate of change of the inductance of the inductor multiplied by the current. As the current through the inductor increases or decreases, the back emf also increases or decreases accordingly.

By utilizing the back emf generated by the ELL-4FG4R7NA inductor, it is possible to filter out and block high frequency signals that might otherwise interfere with communication systems. This is due to the fact that the back emf acts as a barrier, preventing high frequency signals from passing through the inductor. Furthermore, the ELL-4FG4R7NA can also be used as an amplifier, as the induced voltage can be amplified without any distortion due to its high frequency response.

In conclusion, the ELL-4FG4R7NA fixed inductor is an essential component for radio frequency applications. It has a low profile design and can handle up to 25V DC and a wide operating temperature range. It can be used to filter out and block high frequency signals, and can also be used as an amplifier. Its working principle is relatively simple, as it utilizes the back emf generated by the inductor to achieve its purpose.
