Fixed inductors are passive electronic components that are composed of a coil or wire wound around a core, such as iron, ferrite, or air. They are used as part of a circuit to create a preferred electronic set up. They work by concentrating and increasing the current within the circuit to achieve specific outcomes. An example of this would be the production of a radio signal by a transmitting antenna. 

The SCRH4D28-101 is a high-current, radial-leaded, ferrite-core, fixed inductor. This type of inductor is a popular choice for power electronics, especially power factor correction. The SCRH4D28-101 is an 11mm x 6.9mm x 11.7mm fixed inductor with a 400uH inductance value, a 5 Amp dc current, a 0.18 Ohms dc resistance, and a 19.3 Ohms ac resistance.

The application field for the SCRH4D28-101 can be seen in high frequency switching applications where optimal power management is implemented. These applications include DC-DC converters, power supply filters, inverters, motor control systems, resonant converters, and solar systems, as well as other products with high frequency/current specifications. Other applications requiring accurate size and power management components will also benefit from the features of the SCRH4D28-101.

The SCRH4D28-101 works through its core to generate a magnetic field by winding a coil of wire around it. These two elements form an inductor. When a current is sent through the coil, the core creates a magnetic field. This field then creates an opposing force to the electrical current sent to it. As a result, the electrical current is slowed down through the inductor, which increases the current and amplifies the voltage waveforms. This principle is known as inductance. The core of the inductor increases the magnetic field available, which in turn, increases the power that can be used to amplify the current. This helps to reduce the power loss in the transmission line.

The SCRH4D28-101 also features a low profile, which is great for applications requiring limited space. The inductor’s ferrite core offers improved saturation characteristics, which produces a less distorted output waveforms. The wide-body construction of the inductor enables better heat dissipation, and its radial leads make it much easier to install into a circuit board. Thanks to its air gap, stress is reduced when the core is subjected to high temperatures.

The SCRH4D28-101 is suitable for a range of applications, providing better efficiency and heat dissipation than other types of inductors. It is suitable for use in high frequency switching systems and for power factor correction. Thanks to its low profile, the SCRH4D28-101 is an excellent choice for applications where space is at a premium. With its ferrite core and improved heat and saturation characteristics, it offers more efficient results in a range of applications.
