PC and Server

Interface protection, power conversion, and signal integrity for desktop, workstation, and rack-server motherboards.

Server and PC motherboards demand reliable interface protection on every external connector, clean step-down conversion across multiple rails, and management-side discretes that survive long product life. Magnias supplies discrete and integrated parts across thirteen product lines that fit these designs, from input power MOSFETs through ESD on every USB / PCIe / Ethernet port to the small-signal transistors and logic gates behind fan, LED, and BMC control.
