(2) DC current for an approximate T of 30 C at +75 C Ambient with no core loss. See Chart 2 for derating of IIdc 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 (Vs) across the inductor. This value represents the Vs at 100 kHz necessary to generate a core loss equal to 10% of the total losses for 30C rise. For other frequencies and operating levels see Chart 2. (Note: skin effect losses not included.) (5) Energy storage (J) at ISAT. For other current levels see Chart 1. (6) Maximum D.C. resistance at +20 C. www.eaton.com/electronics 2
