1. Open Circuit Inductance (OCL) Test Parameters: 100 kHz, 0.1 Vrms, 0.0 Adc, +25 °C

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 125 °C under worst case operating

conditions verified in the end application.

4. K-factor: K-factor: Used to determine Bp-p for core loss (see graph). Bp-p = K * L * ΔI. Bp-p: (mT), K:

(K-factor from table), L: (Inductance in μH), ΔI (Peak to peak ripple current in Amps)..

5. Part Number Definition: DR1030-xxx-R

DR1030 = Product code and size

-xxx= inductance value in μH, R= decimal point,

If no R is present then last character equals number of zeros

-R suffix = RoHS compliant

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
