DESCRIPTION
VRK81B100TH is designed to meet the fast
load transients required by AMD 64-bit
processors and is fully compliant with the latest
AMD64™ processor power specifications. In a
horizontal-mount orientation with a max height
of 0.415”, VRK81B100TH’s unique design and
thermal packaging delivers 100A of power with
efficiencies exceeding 86%. With its ultra low
profile and high current rating, VRK81B100TH
is an ideal fit for a wide variety of applications
including 1U high, or under, rack-mounting
equipment and blade servers.
