Fixed Inductors

A fixed inductor is an electrical component that provides inductance to an electrical circuit. Fixed inductors are usually used to store electrical energy over short or long periods of time. They can also be used to reduce RFI (radio frequency interference) or EMI (electromagnetic interference).

The SPD125-474M is an example of a fixed inductor. It is a highly efficient component that provides up to 4.7µH of inductance. It is a reliable and widely used component, particularly in applications where consistent and reliable performance is required.

Application Fields

The SPD125-474M can be used in many different applications. It is particularly suitable for use in power factor correction (PFC) circuits, switching power supplies, voltage regulators, switched mode power supplies (SMPS) and transformer bridges. It can also be used in applications that require a high-current inductor, such as Filters, LED Drivers, Transformers, Motors and Automotive Electronics. Additionally, the SPD125-474M can be used in noise suppression and EMI/RFI filters, as well as in RF and wireless applications.

Working Principle

An inductor works on the principle of induction, whereby a changing magnetic field induces an electric current in a coil of wire. When an alternating electrical current (AC) is passed through an inductor, it will oppose any changes in current. This is known as inductive reactance, which is measured in ohms. The SPD125-474M has a relatively low inductive reactance, which makes it suitable for use in high-current applications.

In addition to opposing changes in current, an inductor also stores energy in the form of a magnetic field. As AC current passes through an inductor, a magnetic field is generated which increases and decreases in intensity as the current changes direction. This stored energy is known as inductance, which is measured in microhenrys (µH). The SPD125-474M has a relatively high inductance of 4.7µH. The higher the inductance, the more energy is stored and the longer time it takes for the energy to be released.

Fixed inductors are designed for use in applications that require a stable field of energy. The SPD125-474M can be used in applications that require reliable and consistent inductance over time. It is a reliable component that is used in many different applications and is suitable for use in a wide range of fields, from noise suppression to power factor correction.
