SRU1028-151Y

The SRU1028-151Y is a shielded surface-mount power inductor manufactured by Bourns Inc. Designed for high-performance power applications, this component delivers a nominal inductance of 150µH with a tolerance of ±30%. It supports a continuous RMS current of 650mA and maintains a low DC resistance of 518mΩ, ensuring efficient power delivery with minimal loss. The unit utilizes a ferrite drum core and enameled copper wire construction, housed in a compact 10.00mm x 10.00mm x 3.10mm nonstandard package suitable for automated surface-mount assembly.

Engineered for robust thermal performance, the SRU1028-151Y operates across a wide temperature range of -40°C to +125°C and withstands soldering heat up to 260°C for 10 seconds. Its self-resonant frequency reaches 5MHz, making it effective for filtering and energy storage in switching circuits. The component meets Moisture Sensitivity Level 1 standards and is packaged in reels of 1000 units for streamlined manufacturing integration.

This inductor is specifically optimized for input and output stages of DC/DC converters and power supply modules. It is widely utilized in portable communication equipment, camcorders, and LCD television systems where space constraints and thermal stability are critical design factors. Engineers can rely on its consistent electrical characteristics and reliable shielding to minimize electromagnetic interference in dense PCB layouts.
