(2) ETop is rated at 500 kHz except where designated otherwise. (3) The control values of inductance are measured at the operating flux density equal or less than 10 gauss and without DC current. (4) ETop is rated at 250 kHz. (5) ETop is rated at 150 kHz. 6-174 Model HM77 Series OUTLINE DIMENSIONS (Inch/mm) Figure 1 Figure 2 Figure 3 A A A B B B Marking Marking Marking y; ;yy; y;y;y; ; y C D Case Size 1 2 3 4 5 6 7 10 A .340 8.64 .447 11.35 .571 14.50 .625 15.88 .725 18.40 .805 20.40 .669 17.00 .945 24.00 B .340 8.64 .447 11.35 .571 14.50 .600 15.24 .585 14.90 .710 18.03 .669 17.00 .965 24.50 C C D C .250 6.35 .350 8.89 .350 8.89 .360 9.14 .360 9.14 .445 11.30 .400 10.16 .394 10.00 D .260 6.60 .350 8.89 .450 11.43 .500 12.70 .610 15.50 .680 17.27 .560 14.22 .820 20.83 E .330 8.38 .425 10.80 .550 13.97 .580 14.73 .580 14.73 .690 17.53 .665 16.89 .950 24.13 F .270 6.86 .360 9.14 .460 11.68 .510 12.95 .610 15.50 .690 17.53 .560 14.22 .861 21.08 G .060 1.52 .060 1.52 .100 2.54 .100 2.54 .100 2.54 .100 2.54 .100 2.54 .110 2.80 D .005 / 0.13 Coplanarity measured at 4 points.
