Fixed inductors are components used to sustain a certain amount of current over a period of time. They are primarily used in electronics and engineering and are also utilized as key components in many analog circuits. One example of a fixed inductor is the SRU3009-2R2Y, which is a High Current Radial through-hole inductor.This part is designed with a radial construction and contains ferrite core with an internal air-gap, making it capable of handling high temperatures and large current levels. It also utilizes a shield construction to ensure good frequency performance. The size of the inductor is 22x25.7x9.7mm. The SRU3009-2R2Y’s primary application field is in power systems that require high current inductors, including motor drives, power supplies, and high efficiency SMPS systems.In terms of its working principle, the SRU3009-2R2Y is a type of inductor that stores power magnetically when the electrical current runs through its winding. This process creates a constant voltage throughout its winding, which forces electrons to flow continuously at a specified rate and for a period of time. The particular design of the SRU3009-2R2Y allows it to operate at high temperature cycles and still remain stable, guaranteeing the safety and performance of the system.The SRU3009-2R2Y has a wide range of advantages compared to other specific forms of inductors, most notably its high current capability and its ability to maintain good frequency performance. Its small size makes it ideal for uses in compact designs as this size contains a good power density. The design also ensures that it has excellent thermal performance due to its air-gap core, and offers an improved temperature coefficient compared to other components such as film capacitors. Additionally, the SRU3009-2R2Y has excellent current handling capabilities even at low profiles, and its low profile design ensures it has a good spread of the resistance over the winding area.All of these advantages make the SRU3009-2R2Y an ideal choice for applications that require a reliable high current inductor with excellent temperature and frequency control. It is also notable for its price, making it relatively affordable compared to other especially designed high power inductors. Thanks to these reasons, the SRU3009-2R2Y has an established and widespread application in motor drives, power supplies, and high-efficiency SMPS systems.
