Fixed Inductors

Fixed inductors are electrical components with a given inductance value that are available in cylindrical, radial, and axial form factors. They are used extensively in a wide variety of applications, including AC/DC converter, power audio speaker circuits, battery-powered devices, power supplies for incandescent lamp circuits, radio frequency (RF) power amplifiers, telecommunications systems, and antennas. They are particularly useful for stabilizing current or providing electrical isolation by lowering or raising the inductive reactance of the circuit.

5500-476K Application Field and Working Principle

The 5500-476K fixed inductor is designed with a ferrite core and a 15-turn, 16-AWG winding, making it a high-power rating with excellent heat dissipation. It has an inductance of 4.7µH and a maximum DCR of 0.05 ohms. Because of its high-power rating and excellent heat dissipation, this inductor is well suited to applications such as high-power car and home audio systems. It is also ideal for power supplies, bridge circuits, audio amplifiers, and radio frequency (RF) power amplifiers.

Fixed inductors work by resisting changes in magnetic flux. The inductance of a fixed inductor is the proportionality factor between the current and the rate of change of the magnetic flux. The core material used for fixed inductors determines the electrical characteristics of the inductor, including frequency and inductance. The winding material used influences its inductance and winding resistance as well as its electrical and thermal resistance.

The 5500-476K fixed inductor operates by allowing the magnetic field to induce a counter-electromotive force in the winding’s conductors. This counter-emf opposes changes in current. When an AC voltage is applied to the winding, the core stores energy in a small magnetic field created by the current. When an AC voltage is interrupted, the magnetic field collapses and an equal and opposite voltage is generated. This process is known as inductive reactance, and it is the main source of impediment to current flow in an AC circuit.

The 5500-476K operates in a self-regulating way. As the current increases, the turns of the winding interact and its resistance increases, thus limiting the current. This self-regulating behavior keeps the inductor protected from high current or voltage values. This makes the device suitable for applications where large spikes in voltage can occur, such as in high-power audio equipment.

Overall, the 5500-476K is a reliable and robust fixed inductor suitable for applications that require high power ratings. Its ferrite core provides excellent strength and heat dissipation and its 15-turn, 16-AWG winding helps to ensure reliable operation. Its self-regulating design helps to protect it from large spikes in voltage and current and it is suitable for applications such as power supplies, bridge circuits, audio amplifiers, and radio frequency (RF) power amplifiers.
