(2) DC current for an approximate ∆T of 30 °C at +75 °C Ambient with no core loss. See Chart 2 for derating of I Idc with core loss. (3) Peak current for an approximate 30% roll-off in OCL. For other current levels see Chart 1. (4) Applied Volt-Time product (Vµs) across the inductor. This value represents the Vµs at 100 kHz necessary to generate a core loss equal to 10% of the total losses for 30°C rise. For other frequencies and operating levels see Chart 2. (Note: skin effect losses not included.) (5) Energy storage (µJ) at ISAT. For other current levels see Chart 1. (6) Maximum D.C. resistance at +20 °C. (A) (A)
