Open Circuit Inductance (OCL) Test Parameters: 100 kHz, 0.1 Vrms, 0.0 Adc, +25 C 4. K-factor: K-factor: Used to determine Bp-p for core loss (see graph). Bp-p = K * L * I. Bp-p: (mT), K: 2. I : DC current for an approximate temperature rise of 40 C without core loss. Derating is necessary for AC currents. (K-factor from table), L: (Inductance in H), I (Peak to peak ripple current in Amps).. rms PCB layout, trace thickness and width, air-flow, and proximity of other heat generating components will affect the 5. Part Number Definition: DR1030-xxx-R temperature rise. It is recommended that the temperature of the part not exceed 125 C under worst case operating DR1030 = Product code and size conditions verified in the end application. -xxx= inductance value in H, R= decimal point, 3. I : Peak current for approximately 35% rolloff +25 C If no R is present then last character equals number of zeros sat -R suffix = RoHS compliant Dimensions (mm) Part marking: inductance value in uH. R = decimal point. If no R is present then last character equals number of zeroes. wwlly = date code, R = revision level Do not route traces or vias underneath the inductor www.eaton.com/elx 2
