3 / 11 page www.eaton.com/elx 3 DR Series High power density, high efficiency, shielded inductors Technical Data 4315 Effective April 2014 1. Open Circuit Inductance Test Parameters: 100kHz, 0.25V rms, 0.0Adc. 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-μSat 100kHz 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 Part Number Rated Inductance (μH) OCL1 ±20% (μH) I rms 2 Amps I sat 3 Amps Peak DCR4 (Ω) Typ. Volt-μSec5 Typ.
