(2) the saturation current (i sat ) is the current at which the inductance will be decreased by 20% from its initial (zero dc) value. (3) the heating current is the dc current, which causes the component temperature to increase by approximately 50c. this current is determined by soldering the component on a typical application pcb, and then applying the current to the device for 30 minutes. (4) core loss approximation is based on published core data: core loss (pfe) = k1 * (f) 1.338 * (k2 ? i) 2.2546 where: core loss in watt f = frequency in khz k1 and k2 = core loss factor ? i = delta i across the component in amp. k2 ? i = one half of the peak to peak flux density across the component in gauss specifications rohs compliant packaging standard : embossed tape & reel reel: diameter: = 13 (330.2mm) capacity: case size 10,20,25,30,31,32,33,34 = 500 units case size 35,40,43,45,50,60 = 400 units
