Fixed Inductors

A fixed inductor is type of electronic component that stores electrical energy in the form of inductance, a component of electromagnetic energy. Inductors can be used for a variety of purposes in circuit design, such as for impedance matching, impedance bridging, and to filter signals. Fixed inductors, specifically, are a type of inductor that features a fixed inductance value that does not vary with frequency, temperature, or other changes in the circuit.

The 4470R-12H is a type of fixed inductor that is designed for high current applications. It is a two-terminal component that consists of a coil of insulated wire with a ferrite core. As the core material, ferrite is advantageous as it has a high resistance to magnetic fields as compared to air-cored inductors. Because of this, the 4470R-12H is resistant to temperature changes, and also provides excellent shielding for the inductors coil and core.

The specific working principle behind a 4470R-12H fixed inductor is based on Faraday\'s Law of Electromagnetic Induction. This law states that whenever a conductor is placed in a changing magnetic field, a current is induced inside the conductor. This current is determined by the size of the change of the magnetic field and the speed at which it is changing, as well as the property of the conductor itself, in this case, the magnetic properties of the ferrite core.

With a 4470R-12H, the winding of the wire is designed in such a way that the induced current circulates around the ferrite core and produces a strong magnetic field. This magnetic field acts as an opposition to any change in the current passing through the inductor, and thus has the effect of smoothing any discontinuities caused by the passage of current. This provides excellent voltage regulation, and also serves to protect the internal components of the inductor from damage due to changes in the electrical current.

The 4470R-12H fixed inductor is suitable for use in a variety of high current applications, including power supply filtering, DC-DC converter circuitry, and switching circuitry. Its high current capability and excellent current regulation make it ideal for use in circuits that require long-lasting and reliable performance. It can also operate at temperatures in excess of 100 degrees Celsius, making it ideal for use in harsh and extreme environmental conditions.

In summary, the 4470R-12H fixed inductor is an excellent choice for high current applications, due to its excellent current regulation and high operating temperature. Its ferrite core is resistant to magnetic fields, making the component durable and reliable. The working principle behind the 4470R-12H is based on Faraday\'s Law of Electromagnetic Induction, which states that a changing magnetic field induces a current in a conductor. This effect is used to smooth the electrical current, and also to protect the internal components from damage due to sudden changes in voltage.
