Pulse Electronics PH9499xCL SMD High-Frequency Power Inductors feature Litz wire winding and are explicitly designed for Quasi-Resonant Converters. The PH9499xCL inductors offer a 0.95µH to 1.25µH range with 3.5Arms optimized for an 800kHz to 1.2MHz frequency range. The Litz wire limits the ratio of AC-to-DC resistance to 1.25 at 1MHz, so the converter can maximize the benefit of the low 22mΩ maximum DC resistance.
