Fixed Inductors

A fixed inductor, in general, is a device for generating a circuit that stores electrical energy in a magnetic field by passing a current through an inductor. It can also be used to increase or decrease an electrical signal or current. Inductors can be found in applications such as audio systems, electrical engineering, and other industrial applications.

The 4470-49F is a type of fixed inductor, which is specifically designed for easy mounting, light weight, and superior performance. The 4470-49F is typically found in high current DC applications such as automotive and audio/video systems. It is also frequently used for automotive audio systems or other miniaturized high current applications.

Application Field

The 4470-49F fixed inductor is tailored to provide all kinds of audio power amplifiers and low frequency switching applications. It is highly reliable and has superior power efficiency with excellent noise suppression and wide operating temperature. It also features a small size and is easy to mount via the included adhesive mount pads.

The 4470-49F inductor is also widely used in automotive, high current and audio/video applications. It\'s ideal for use in vehicles to improve sound clarity and provide superior power efficiency. Additionally, it is suitable for audio/video equipment, professional audio systems, switching power supplies, and sound systems.

In terms of power efficiency, the 4470-49F is designed to optimize inductance with fewer turns of the copper wire, reducing power losses and allowing for a lower profile. It also features an extremely low ESR (equal to self-resonant frequency ) which is under 0.01 ohm, allowing for higher current handling while maintaining excellent thermal stability and reliability.

Working Principle

An inductor in general stores energy in a magnetic field which it produces when an electrical current passes through its coil. The 4470-49F inductor works on the principle that when a current passes through the coil, a magnetic field is generated, with the magnetic field strength proportional to the amount of current passing through it. This stored energy in the form of electromagnetic field will be released back into the circuit as the current flow stops.

When applying a DC current of constant magnitude and changing its direction, the magnetic field around the coil will shift from one direction to the other. This shift in the magnetic field will induce a voltage in the coil, which is known as the back EMF (electromotive force). As a result, the back EMF will oppose the change of the current, and as a result, the current’s direction will be inhibited. This is known as the inductive effect.

The inductive effect of the 4470-49F inductor is further increased by the high inductance of the device. This high inductance will require more time and energy to overcome the inductive effects and consequentially supports both the noise suppression and a wider operating temperature range.

Conclusion

The 4470-49F fixed inductor is a highly reliable and lightweight device designed to provide superior performance in a variety of high current applications. It is especially suited for automotive and audio/video applications due to its superior power efficiency, excellent noise suppression, and wide operating temperature range. Its small size and easy mounting further increases its flexibility across a number of applications.
