1. Open Circuit Inductance Test Parameters: 100 kHz, 0.25 Vrms, 0.0 Adc.

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-μsec 100 kHz 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
