Notes:
(1) Open circuit inductance test parameters: 100kHz, 0.250Vrms, 0 Adc.
(2) DC current for an approximate ∆T of 30°C at 75°C Ambient with no core loss. See Chart 2 for derating of 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 100kHz 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.
