Fixed inductors are electrical components used to store and control energy by exploiting the physical properties of inductance. They are also known as chokes, coils, or reaction coils. Their primary purpose is to "react" to an electrical current and prevent the uncontrolled spread of electrical charge to other components, resulting in the desired reaction.

The 4470R-13J is an example of a fixed inductor. It is a high-frequency inductor rated to a wide range of current up to 13A, with an inductance ranging from 0.01 μH to 100 μH. The 4470R-13J utilizes a series of windings in both the inductor core and the external components to create an electrically-coupled system. The windings are wound in such a way to take advantage of the properties of inductance, which is the ability of a changing current through a conductor to induce a magnetic field, and vice versa. This magnetic field can then be utilized to create a specific reaction.

In a typical application, the 4470R-13J is used to produce a wide range of frequencies, mostly between 50kHz to 5MHz. This range covers the most widely used frequencies in the radio and telecommunications industries. The frequency output is determined by the number of turns of wire on the inductor core, with higher numbers of turns corresponding to higher frequencies. When connected to a power supply and driven with a signal, the 4470R-13J acts as an impedance converter, regulating the flow of current throughout the circuit. The designed range of frequencies also makes the 4470R-13J ideal for noise-filtering applications.

The 4470R-13J is commonly found in electronic systems such as mobile phones, cell phone base stations, television sets, and portable radio receivers, where it is used to filter out noise, regulate current, or as an impedance converter. The 4470R-13J is also useful in motor control applications, where its high frequency capabilities are used to drive the motor coils. In such applications, the 4470R-13J is used to ensure that the speed and current of the motor remain within its specified range, even if the input signal changes.

Overall, the 4470R-13J is a versatile fixed inductor with applications across a wide range of frequencies. Its ability to regulate current and act as an impedance converter makes it suitable to be used in a variety of electronic systems. Knowing the working principle of the 4470R-13J and the fields where it is applicable can help in its successful implementation.
