2 / 8 page DRA Series High Power Density, High Efficiency, Shielded Inductors Magnetics Solutions For Automotive Applications (1) Open Circuit Inductance test parameters: 100kHz, 0.25V, 0.0Adc, tolerance is ±20% (2) Irms: DC current for an approximate ∆T of 40°C without core loss. Derating is necessary for AC currents. PCB layout, trace thickness and width, air-flow, and proximity of other heat generating components will affect the temperature rise. It is recommended that the temperature of the part not exceed 165°C under worst case operating conditions verified in the end application. (3) Isat Amperes peak for approximately 30% rolloff (@25°C) (4) Isat Amperes peak for approximately 40% rolloff (@125°C) (5) DCR limits @ 25°C (6) K-factor: Used to determine B p-p for core loss (see graph). B p-p = K*L* ∆I, B p-p(mT), K: (K factor from table), L: (Inductance in µH), ∆I (Peak to peak ripple current in Amps). (7) Part Number Definition: DRAxxx-xxx-R DRAxxx = Product code and size; -xxx = Inductance value in uH; R = decimal point; If no R is present, third character = # of zeros. -R suffix = RoHS compliant Part Number Rated OCL (1) Irms (2) Isat (3) Isat (4) DCR (5) K-factor (6) Inductance µH Amperes Amperes Amperes ( Ω) +/-20% Typ.
