?Storage temperature range:-40°C to +125°C ?Operating temperature range:-40°C to +125°C (range is application specific)

?Solder reflow temperature:+260°C max. for 10 seconds max.Packaging

?Supplied in tape and reel packaging,1350 (DR73),1100 (DR74),600 (DR125),and 350 (DR127) per reel

(1) Open Circuit Inductance Test Parameters:100kHz,0.25V rms ,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
