Fixed inductors are components that are used to store electrical energy in an electromagnetic field and are found in almost any electronic system. The 28474C inductor is a category of fixed inductors, and is specifically used in applications like power conversion, DC-DC converters, switching power supplies, and more. This article will explain the application field and working principle of the 28474C inductor to provide a better understanding of how it functions.

The 28474C inductor is used as an input reactor in various types of power conversion systems, and as a snubber in power switching applications. In DC-DC converters, it is used to improve converter efficiency, reduce power losses, provide surge protection, and improve power factor. In switching power supplies, it is often used as an input choke, which will help dampen the input current and thus reduce the noise. The 28474C also has a wide operating temperature range, from -40℃ to +105℃, meaning it can be used in a variety of conditions.

The primary purpose of an inductor is to store energy in its magnetic field. It is constructed from a wire core, often made of either Iron or Ferrite, which is then wound with more wire. When an alternating current is passed through the inductor, the magnetic field around the winding will increase and decrease, passing energy back and forth between the inductor and the current source.

The number of turns of wire around the core and the material of the core itself determine the inductance of the coil. The higher the number of turns, the greater the inductance. The 28474C inductor is designed to provide a high inductance and a low DC resistance, which makes it suitable for power applications. As an input reactor, it is able to reduce the peak voltage spikes that occur during the conversion process, protecting other components from damage.

The 28474C is also suitable for snubber applications where it filters the high frequency noise generated by the switching operation. A snubber is a type of inductor connected in series with a switching element, which can reduce the voltage and current surges. The 28474C inductor uses its high inductance and low DC resistance to absorb the transient energy and reduce the voltage and current spikes, protecting the switching element and other components.

The 28474C inductor is a versatile component that offers a variety of advantages. It can be used in power conversion applications to provide surge protection, improve effectivity, and reduce power losses. It can also be used in switching power supplies to eliminate noise. Additionally, the 28474C can be used as a snubber device that helps protect switching elements from transient voltage and current surges. The 28474C offers a wide operating temperature range, allowing it to be used in a variety of environments.
