High power density, high efficiency, 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. 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 approximate 30% roll off at +20 °C. 4. DCR limits @ +20 °C. 5. Applied Volt-Time product (V-μ s) across the inductor. This value represent the applied V-μsec 100 kHz necessary to generate a core loss equal to 10% of the total losses for 40 °C temperature rise. 6.
