(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 apply 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 rohs compliant specifications inductance 100khz, 0.1v dcr (1) i sat (2) heating (3) core loss (4) @ 0 adc @ i sat (m ? ) @ 25c current factor part ( h 20%) ( h) (adc) (adc) number typ. min. typ. typ. max. ? t =50c k1 k2 fig.
