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-μs) 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. Part number definition: DRxxx-yyy-R - DRxxx = product code and size, - yyy = inductance value in μH, - R = decimal point. If no R is present, third character = # of zeros - “-R” suffix = RoHS compliant 2 www.eaton.com/electronics DR High power density, high efficiency, shielded drum core power inductors Technical Data 4315 Effective September 2017 Product specifications Part Number DR74-R33-R DR74-1R0-R DR74-1R5-R DR74-2R2-R DR74-3R3-R DR74-4R7-R DR74-6R8-R DR74-8R2-R DR74-100-R DR74-150-R DR74-220-R DR74-330-R DR.
