Fixed Inductors

Fixed inductors, often referred to as coils, are passive components comprised of a conducting wire wrapped around a core material. This creates a magnetic field when a current is passed through it. This magnetic field is used to direct and control the current and can also be used to store energy, allowing them to act as electrical components or coils. Fixed inductors are used in many applications including filters, transformers and one of the most popular types - the IHB5EB472K.

IHB5EB472K Application Field and Working Principle

The IHB5EB472K is a general-purpose, radial-style, Leaded Inductors ideal for applications such as switch mode power supplies, DC/DC converters and electronic ballasts. It features a nominal inductance of 4.7uH and a maxim operating temperature of 125˚C. It’s designed for noisy environments such as loudspeakers, VCRs, TVs, etc. and is particularly useful for applications where the inductance needs to remain constant over varying signals.

The IHB5EB472K is based on a fixed inductor design, and is circular in shape. It consists of a ferrite core material, or magnetic layer material, with a winding of copper wire around the core in a spiral design. The core material is chosen so that it has low electrical conductivity, which prevents eddy currents in the core and helps reduce heating. The copper winding is electrically isolated, thanks to the non-conductive tape roll at the center. In addition, each end of the winding is connected to two insulated terminals.

The IHB5EB472K’s working principle is also the same as other types of fixed inductors. When an alternating current is applied, the inductor creates a constantly rotating magnetic field, creating a second-order voltage that is proportional to the applied current. This second-order voltage will act in opposition to the applied voltage, creating a constant voltage drop across the inductor. This voltage drop results in energy storage (magnetic field) and is what makes the IHB5EB472K useful as it ensures constant, stable operation over the life of the component.

The IHB5EB472K is an efficient and reliable component for many applications and it can be used in a variety of electronic equipment. Its compact size, low cost, and high temperature coefficient make it a great choice for projects that need precision control of voltage and current. Additionally, it can be used in noise-sensitive equipment applications without affecting the performance of the device.
