Dual winding, high power density, shielded drum core power inductors www.eaton.com/electronics Product specifications 1. Open Circuit Inductance Test Parameters: 100 kHz, 0.25 Vrms, 0.0 Adc Parallel: (1,2 -4,3) Series: (1-4) tie (2-3) 2. RMS current for an approximate DT of 40 °C without core loss. It is recommended that the temperature of the part not exceed +125 °C. 3. Peak current for approximately 30% roll-off at +20 °C DCR limits @ +20 °C 5. Applied Volt-Time product (V-µs) across the inductor. This value represents the applied V-µs at 100 kHz necessary to generate a core loss equal to 10% of the total losses for a 40 °C temperature rise. 6. Turns Ratio (1:3):(2-4) 1:1 7.
