Pulse, YAGEO's high-frequency inductor is specially designed for the quasi resonant converter power module, which directly converts from 48 V to silicon core voltage. With its compact size (11.2 mm x 9.75 mm x 7.6 mm) and 1.1 mm isolation design features, it allows the module to be installed under the inductor, which can achieve a power density of more than 240 w/in3 in the final power module design. In addition, an inductance tolerance of 6% is achieved to maximize the benefits of the resonant topology.
This tight tolerance comes from the number of winding turns selected, resulting in a high saturation current (> 18a), so high overcurrent can support a short time without affecting performance. PH9499 series solves many limitations by using high-frequency grade, low core loss, ferrite material and fine range Litz wire, and specially selects and optimizes the performance of user modules to make them more than 90% efficient
