Fixed inductors, also known as coil, has been widely used in various kinds of electronic circuits, and are one of the most important components. SCB75F-120 fixed inductors are one of the most commonly used fixed inductors. This article will explain its application field and working principle.

SCB75F-120 fixed inductors are mainly used in areas related to electricity and magnetism. Typical application fields include:

• Power converters and rectification – SCB75F-120 inductors are suitable for 11A and 470uH high current applications due to its excellent thermal dissipation.

• Automotive industry – The use of SCB75F-120 fixed inductors in automotive industry are mainly used in the application of engine control module.

• EMI filters, DC-DC converters, voltage regulators – SCB75F-120 fixed inductors are also often used in these industry as an important component.

In its simplest form, a fixed inductor is an electrical component consists of a wrap of wire around its core (magnetic material). In most cases, the core is made up of a magnetic material like iron, ferrite or ferrite, while the wire is simply an electrical conductor. The conductor and core together form an electrical circuit, which is used in the application to cause an electromagnetic effect. This electromagnetic effect occurs when a current passes through the wire of the inductor, inducing a magnetic field around the inductor and creating a unique electrical current path.

When an electrical current passes through the wire of an inductor, it induces a magnetic field around the inductor. This magnetic field then induces an opposing voltage in the electric current, opposing the current flow. The magnitude of opposing voltage is proportional to the rate of change of current, which is called inductance. In other words, it is this opposing voltage that increases as current is increased at a constant rate. The effect of this opposing voltage limits the rate at which current flows, and thus helps to regulate the power of any electric circuits it is part of.

Inductors can be used in two ways. First, they can be used to filter out electrical noise, also known as radio frequency interference (RFI) in electronics applications. This is done by placing the inductor in the path of the current flowing to and from the component being protected, thus effectively filtering the noise. Second, inductors can also be used to store and release energy, such as in applications involving transformers and UPS units. This is done by using the unique electrical characteristic of the inductor to store energy in its magnetic field and then releasing this energy in pulses over time.

SCB75F-120 fixed inductors are widely used for their excellent thermal dissipation properties in power converters and rectification, automotive industry, and EMI filters, DC-DC converters, voltage regulators. In terms of working principle, the magnetic field induced by the current in the inductor causes an opposing voltage, limiting the rate of current flow, and providing electrical noise filtering or storage and releasing of energy.
