High-Frequency Litz Wire Resonant Inductors – PH9499_CNL Series

Pulse Electronics, a YAGEO Company, high-frequency inductors are designed specifically for quasi-resonant converter power modules, converting directly from 48 V to silicon core voltages. Through its compact size (11.2 mm x 9.75 mm x 7.6 mm max) and its 1.1 mm stand-off design feature that allows components to be mounted beneath the inductor, a power density of over 240 W/in³ can be achieved in the resultant power module design. Additionally, an excellent 6% inductance tolerance is achieved to maximize the benefits of the resonant topology. This tight tolerance, which arises from the selected number of winding turns, results in a high saturation current (>18 A), so a high overcurrent can be supported for a short duration without compromising performance. The PH9499 series addresses many limitations by using a high-frequency grade, low core loss, ferrite material and a fine gauge litz wire, specifically selected to optimize the performance of the user's module, allowing them to achieve over 90% efficiency.
