Fixed Inductors

Inductors, or coils, are a type of fixed electrical component that store energy when a voltage is applied. The SC2220-472 is a fixed inductor used in a variety of applications, ranging from consumer electronics and power converters to automobile and military use. The SC2220-472 has a coil diameter of 4.7 mm and an inductance of 2.2 μH. In this article, we will look at its application field and examine how it works.

Application Field

The SC2220-472 is used in a wide range of applications, with several key areas gaining particular benefit from using it.

Consumer Electronics

The SC2220-472 is a perfect choice for a range of consumer electronics products due to its small size and high inductance. It is often used as an input filter in audio systems, helping to reduce any noise in the audio signal. In addition, it is used in RF communication systems, where its high inductance allows it to filter noise while allowing signals to pass through.

Power Converters

The SC2220-472 is also used in power converters, such as DC/DC converters and AC/DC and DC/AC inverters. In these systems, it acts as a choke, helping to limit the current flow to the load while maintaining a constant voltage. It can also be used as a filtering element, helping to reduce the noise in the output.

Automobile

The SC2220-472 is also used in a range of automotive systems, particularly those involving high electrical current. It is used as a filter in the electronic spark systems of modern engines and as an inductor in ECUs and ABS systems.

Military

The SC2220-472 is also used in a number of military applications, ranging from communication and navigation equipment to guided missiles and drones. In these cases, it is used to filter signals and absorb high amounts of electrical energy.

Working Principle

The SC2220-472 works on the principle of induction. When an alternating voltage is applied to the coil, a changing magnetic field is created which in turn induces an electrical current in the coil itself. This electric current is known as an induced current. The amount of induced current in the coil is proportional to the frequency of the voltage applied and the number of turns in the coil. In the case of the SC2220-472, the inductance value of 2.2 μH means that it can effectively filter noise from voltages with frequencies up to 1 MHz.In addition, the SC2220-472 can be used to limit the current flow to a particular load. By introducing an inductor into the circuit, the circuit effectively has two paths for the current to take. One path is through the inductor, which offers some resistance to the flow of current, while the other path is through the load, which offers very little resistance. As a result, more current is able to flow through the path of least resistance, which is through the load, thus limiting the current flow.

Conclusion

The SC2220-472 is a versatile fixed inductor that is used in a wide range of applications, ranging from consumer electronics and power converters to automobile and military use. It works on the principle of induction and is able to filter noise from voltages with frequencies up to 1 MHz and limit the amount of current flowing to the load.
