1. When ordering, specify a packaging code:
TA7618-ALD
Packaging: D = 13â³ 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 âSoldering Surface Mount Componentsâ before soldering.
