(2) 2*lk is two times of leakage inductance [winding (1-2) with pins 4 & 3 shorted] @100khz, 0.1v. (3) dcr is measured at 25c at points a and b. (4) i sat-1 is the dc current which causes ls to drop to ls @ i sat-1 . (5) i sat-2 is the dc current which causes 2*lk to drop to 2*lk @ i sat-2 . part ls (1) ls @ i sat-1 2*lk (2) 2*lk @ i sat-2 dcr (3) i sat-1 (4) i sat-2 (5) number (nh 20%) (nh min.)
