Fixed Inductors

Inductors, also called coils or reactors, are an important component of most electrical systems. Inductors stores energy in an electromagnetic field and essentially acts as an electronic component that helps to regulate current or voltage. A Fixed inductor, often referred to as a fixed-value inductor, is a type of inductor which maintains a fixed inductance even when the current or voltage applied to it changes. These inductors are typically found in low-cost power supplies and utilize a coil of wire between two magnetically connected cores.

In particular, the SRU1028A-220Y is a fixed inductor from Coilcraft, Inc. This inductor offers low DC resistance (1.5 ohms) and a wide, flat impedance-versus-frequency curve. It isl made with a high temperature construction with excellent flux stability. The SRU1028A-220Y offers a double-shielded construction that provides superior electrical and mechanical performance.

Application Field of SRU 1028A-220Y

The SRU1028A-220Y fixed inductor is primarily used in switched-mode DC-DC converters that require high ripple current and low DCR. Examples of these converters are DC to DC regulators, DC-DC battery chargers, DC-DC voltage converters, and solutions for automotive applications. It can be used in power supplies such as notebook computers, mobile phones, TVs, and other home electronics. It can also be used in LED modules, PFC circuits, and other related applications.

Working Principle of SRU 1028A-220Y

The SRU1028A-220Y fixed inductor works by creating a coil of wire between two magnetically interconnected ferromagnetic cores. This arrangement creates a magnetic field that stores energy when current is applied. When the current through the inductor increases, the magnetic field increases, and the inductor stores more energy. When the current drops, the inductor releases the stored energy. This release of energy causes an opposition to the decrease in current, thus maintaining the current at a steady rate.

The SRU1028A-220Y’s double-shielded construction provides superior electrical and mechanical performance. The high temperature construction of the inductor ensures that it can handle higher levels of current compared to traditional ferrite-core inductors. Additionally, the flat impedance-versus-frequency curve enables the device to handle complex waveforms with ease.

In conclusion, the SRU1028A-220Y fixed inductor is an efficient and versatile component for a variety of electronic applications. Its high temperature construction, low DCR, and flat impedance-versus-frequency curve make it a great choice for designs requiring high ripple current capabilities.
