Features

· Lowest DC resistance with significantly reduced AC losses, outstanding performance at high frequencies

· Higher inductance in the same PCB footprint; smaller footprint for the same inductance, ideal for high-density layouts

· Substantially enhanced Irms (temp rise current) and Isat (saturation current), resulting in lower heat generation and higher efficiency

Applications

· Servers, PC motherboard VRM/VRD, CPU core power delivery (Core Application)

· High-density high-current power modules, high-performance FPGA/SoC power stages

· Industrial high-power systems requiring high efficiency and low temperature rise

· Automotive electronics and telecom equipment with strict dimensional constraints
