1. Open Circuit Inductance Test Parameters: 100kHz, 0.25Vrms, 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
