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
