Fixed Inductors: IHD3ER472L

Inductors, often found in the form of a coil of wire, are used in electrical circuits as components to store energy in magnetic fields and to provide a reactive electrical element. A fixed inductor is an inductor with a fixed inductance, which means it is a passive electrical component with a single electrical characteristic. The IHD3ER472L is a fixed inductor which is composed of a coil of wire and ceramic body, and is used in a wide variety of applications.The inductance of the IHD3ER472L is 47uH, with a tolerance of +/-20%, and a current rating of 3A. It is a non-polarized component, meaning it can be connected in either direction in a circuit. Being a ceramic body inductor, the IHD3ER472L is popular for high frequency applications as it does not suffer from the same signal loss as typical low frequency inductors. It also has a low profile which makes it ideal for building smaller circuits, and can easily fit within a range of PCB designs.The specific application of the IHD3ER472L highly depends on what the end device is trying to accomplish. The primary use in commercial applications is in signal filtering for AC power supplies, providing clean and accurate signal output. It is also commonly used within audio amplifiers, limiting voltage spikes which can damage other components and create unwanted noise and distortion. In a consumer device, it is often used to reduce the size and profile of the device by providing smaller and more efficient filtering and routing of sound, video, and data signals.When it comes to the working principle of a fixed inductor, the most important concept to understand is the electromagnetic field. When electrical current is applied to the IHD3ER472L, it creates a magnetic field which stores the power and creates an opposing force on the electrical current. This opposing inductance to the flow of current is known as inductive reactance, and acts to resist any changes in the flow of current, providing a stable and protected current in the circuit.The IHD3ER472L can also be used for various other applications, such as providing power to wireless systems, isolating circuits, and providing impedance protection. It can also be used for harmonic and noise attenuation, especially in industrial and commercial applications where it is used to reduce electromagnetic interference from other nearby devices.Overall, the IHD3ER472L fixed inductor is an efficient electrical component which provides a variety of uses in a wide range of applications. It has a low profile and is used for both high and low frequency applications, making it a versatile and useful component for building electrical circuits. By understanding its working principle and the capabilities it provides, engineers can easily pick the right fixed inductor for their designs.
