Fixed Inductors are some of the most common and important pieces of electronic equipment on the market today. They are used in all manner of electronic devices, from radios to televisions and even cell phones. The 4470-09F is a type of fixed inductor that can serve a variety of different purposes. This article will discuss the application field and working principle of the 4470-09F.

The 4470-09F is an electrically-insulated wire winding around a ferrite core. It has a rated inductance of 04-07 mH and a rated DC resistance value of around 5-6 ohms. This inductor is a surface-mount version, so it can be soldered onto a printed circuit board and then connected to components. It is suitable for use in consumer electronics such as TVs, audio equipment, and computers.

The application field of the 4470-09F is quite vast. It is mainly used as a smoothing inductor for the output of noisy switching power supplies. It can also be used to help regulate the voltage of power supplies and to reduce EMI (Electromagnetic Interference). Another common use for the 4470-09F is as a filter inductor in audio equipment, where it helps to filter out noise and other interference from the signal.

In terms of its working principle, the 4470-09F follows the traditional basic functions of an inductor. It stores energy in the form of a magnetic field, when a changing current passes through it. The stored energy creates a counter-emf, which acts as a protective measure against any voltage fluctuations occurring in the circuit. The inductor’s DC resistance value also helps to limit the amount of current passed through the inductor.

Also inherent in the 4470-09F is its ability to limit inrush current, or ‘surge’, on start up. This is a feature that is important in many electronic devices, as sudden surges of electricity can damage delicate components. The inductor will absorb the initial ‘surge’ current, allowing the device to start up smoothly without any damage.

The 4470-09F is also relatively small compared to other inductors, making it very useful in compact devices such as cell phones. Its surface-mount design makes it perfect for use in such devices, as it can be easily attached to the printed circuit board and connected to components.

Overall, the 4470-09F is a versatile and useful fixed inductor, suitable for use in a variety of different applications. Its ability to regulate voltage and current, as well as its small size, make it a valuable component in many electronic devices. As such, it is an important piece of equipment in the world of fixed inductors.
