1. When ordering, specify a

packaging code:

TA7608-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, 0.1Vrms,

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.
