DR Series High power density,
high efciency, shielded inductors
Technical Data 4315
Effective April 2014
1. Open Circuit Inductance Test Parameters: 100kHz, 0.25V
rms
, 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
