When ordering, specify a packaging code: 2 TA7618-ALD Packaging:D =13″ machine ready reel. EIA-481 embossed plastic tape. B =Less than full reel. In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter D instead. 2. Inductance is for the primary, measured on an Agilent/HP 4284 at 100 kHz, 0.1 Vrms, 0 Adc. 3. Leakage inductance measured between pins 2 and 3 at 100 kHz, 0.1 Vrms, 0 Adc with pins 8 and 5 shorted. 4. Isolation (hipot) measured between windings for one minute. 5.DC current that causes an inductance drop of 30% (typ) from its value without current 6. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
