Fixed inductors are widely used in the electronics industry in various applications. The 28105C is a cost-effective choice, with a wide range of uses. In this article, we will look at the 28105C, its application field, and its working principle.

Application Field
The 28105C is a high Q, low-resistance, low-profile, low-cost, fixed inductor ideal for circuit designs where cost and physical size are critical. It is suitable for both AC and DC circuits and is designed for use in wide band applications such as filters, broadband amplifiers, and transceivers. It is a great choice for consumer, commercial, industrial, and aerospace applications. Its low ESR makes it well-suited for noise suppression and audio applications.

Working Principle
The 28105C is an inductor with a core material of ferrite, which consists of iron-oxide particles in the form of an organic binder. This core material has a very high inductance to volume ratio with very low losses. When an electrical current is applied to the inductor, an electromagnet is formed, and this in turn creates a magnetic flux in the core material. The changing magnetic flux induces a voltage in the winding, which is inversely proportional to its inductance. Therefore, the more the windings, the higher the inductance, and the lower the voltage induced by the winding.

The 28105C also has a very low profile of 2.75mm, allowing for it to be used in many PCB designs. The inductor is also available in various configurations such as single-winding, dual-winding, and three-winding. This makes it suitable for a wide range of applications.

In summary, the 28105C is a cost-effective and low-profile choice for inductor applications in audio, noise suppression, filters, broadband amplifiers, and transceivers. It has a high Q, low-resistance, low-profile, and low-cost. Its low ESR makes it well-suited for noise suppression and audio applications. The 28105C is also available in various configurations, making it suitable for a wide range of applications.
