1. When ordering, please specify packaging code:
ZE2432-AED
D = 13″ machine-ready reel. EIA-481 embossed plastic
tape (200 parts per full reel). Quantities less than full
reel available: in tape (not machine ready) or withleader and trailer ($25 charge).
2. Inductance is for the primary, measured at 200 kHz, 0.1 Vrms, 0 Adc.
3. DC current that causes an inductance drop of 30% (typ) from its value
without current.
4. DCR values specified with windings connected in parallel.
5. Leakage inductance is for the primary winding (connected in parallel)with the secondary windings shorted.
6. Isolation (hipot) measured between primary windings (connected inparallel) to secondary windings (connected in parallel).
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
Packaging:

Connect pin 2 to 1, 4 to 5,
10 to 9, and 6 to 7 on PC board.
