SRU1028-1R0Y: A Reliable Inductor for High-Speed Circuits
The SRU1028-1R0Y is a premium surface mount device (SMD) power inductor engineered to deliver exceptional high-frequency performance, superior energy efficiency, and reliable operation in a wide range of electronic systems. With an inductance of 1.0 μH (directly indicated by "1R0"), it is designed to meet the demands of power conversion, signal filtering, and EMI suppression in high-speed circuits.
Key Technical Attributes
The SRU1028-1R0Y features a precisely calibrated 1.0 μH inductance, optimized for high-frequency and medium-power applications. Housed in a compact 1028 (1.0mm x 2.8mm) surface-mount package, it integrates seamlessly into high-density PCBs, making it ideal for consumer electronics, communication modules, and industrial control systems. Crafted with a high-grade ferrite core and efficient copper windings, it ensures low DC resistance (DCR) to minimize power loss and excellent saturation current performance to handle transient currents. Its robust construction enhances thermal stability and mechanical durability, while operating reliably across a temperature range from -40°C to +125°C, adapting well to harsh environments.
Notable Performance Advantages
This SMD inductor excels in high-speed circuits, offering superior frequency response to maintain stable performance in GHz-range applications-critical for 5G devices, data center equipment, and high-speed communication systems. Its low DCR ensures minimal energy loss, improving overall system efficiency and reducing heat generation, which is vital for compact, heat-sensitive devices. The SRU1028-1R0Y also boasts excellent noise suppression capabilities, reducing electromagnetic interference (EMI) in sensitive circuits to preserve signal integrity. Additionally, its compact form factor supports miniaturization, making it suitable for space-constrained products, and its RoHS-compliant design aligns with global environmental standards.
Diverse Industry Applications
In consumer electronics, the SRU1028-1R0Y enhances power management in smartphones, laptops, and wearable devices, ensuring stable performance in high-speed data processing. In telecommunications, it plays a key role in 5G base stations, routers, and optical transceivers, supporting efficient power conversion and signal filtering. For industrial systems, this inductor optimizes performance in automation controllers and sensor modules, where reliability in high-frequency environments is paramount. It also contributes to automotive electronics, aiding in the operation of advanced driver-assistance systems (ADAS) and in-vehicle infotainment.
