(2) the rated current (i rated ) 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 40c. this current is determined by soldering the component on a typical application pcb, and then applying the device for 30 minutes. (4) core loss approximation is based on published core data: core loss = k1 * (f) 1.77 * (k2 ? i) 2.21 where: core loss in watt f = switching 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 packaging standard : embossed tape & reel reel: diameter: = 13 (330.2mm) capacity: case size 10,40 = 1000 units case size 20,30,60 = 800 units case size 50,55,75 = 500 units case size 70,80 = 350 units ordering information inductance code: first 2 digits are signifcant. last digit denotes the number of trailing zeros. for values below 10h, r denotes the decimal point. case size model series tr - tape & reel packing 13 - 13 reel lead-free hm69 - 50 r10 lf tr13 rohs compliant
