(1) Open Circuit Inductance Test Parameters: 100kHz, 0.25Vrms, 0.0Adc.
(2) RMS current for an approximate ∆T 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-µS
at 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
