17474C

Fixed Inductors

The 17474C is an inductor used in the field of electronics. It is a fixed inductor, meaning that it retains its design characteristics over its lifetime. An inductor is a device which uses the principle of electromagnetism to create and store energy.

The windings on an inductor consist of wire and magnetic core material, and serve to create a magnetic circuit. This magnetic circuit stores energy in its magnetic field. Current is passed through the windings, creating a magnetic field. When the current is removed, the magnetic field collapses, releasing energy. This process is known as electromagnetic induction.

There are two main types of fixed inductors; air-core and ferrite-core inductors. Air-core inductors are wound on plastic or ceramic rods, creating a magnetic field. At high frequencies, an air-core inductor will have the highest inductance. However, it is more prone to stray fields and noise, limiting its applications in higher power circuits.

Ferrite-core inductors are wound on a ferrite core material, creating a stronger magnetic field. Ferrite-core inductors have lower inductance than air-core inductors, but they are rugged, able to handle higher power and temperature ratings. The 17474C is a ferrite-core inductor, usually used in power supplies, pre-amplifiers and buffer circuits.

Inductors are rated by inductance and current. The 17474C has an inductance of 4.7uH, and a DC current rating of 1.5A. It should be used within these values; exceeding these values will damage the device. Many inductors have a tolerance rating, which indicates the accuracy of the inductance value. The 17474C has a tolerance of 10%, meaning that the inductance will not vary more than 10% from the 4.7uH specification.

When selecting an inductor, several factors need to be considered. The inductance value is important, as it determines the amount of energy that can be stored. The current rating is important, as it determines how much power the inductor can handle. Lastly, the tolerance rating is important, as it indicates how accurate the inductance value will be in practice. With the 17474C, these three factors are 4.7uH, 1.5A and 10%, respectively.

The 17474C has a wide range of applications in the field of electronics. It is often used in power supplies, buffer circuits, and pre-amplifiers. It is a ferrite-core inductor, meaning that it is rugged and can handle high power and temperature ratings. Its inductance is rated at 4.7uH with a 10% tolerance, and it can handle a DC current of 1.5A.
