This document describes the PSR1009 series of SMD power inductors from P&Z Electronic. The inductors are designed for low resistance and high current applications and provide magnetic shielding. They are available in inductance values from 0.22uH to 10uH with current ratings ranging from 55A to 5A. The inductors comply with RoHS and REACH standards and are suitable for applications in graphics cards, PCs, and servers. Custom specifications are available and the inductors are packaged on tape and in reels for automatic mounting.
