(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
