1. When ordering, please specify a packaging code:

JA4631-BLD

Packaging: D = 13″ machine ready reel. EIA-481 embossed plastic

tape (600 per full reel).

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 from pins 4– 3 at 1 kHz, 0.1 Vrms.

3. DCR is for each winding of the primary and secondary.

4. Leakage inductance is for the primary windings, measured from pins 1

with all secondary windings shorted.

– 4

5. Based on Bsat of the core at 25°C and the number of turns on winding 4

6. Electrical speciﬁcations at 25°C.

-3.

Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
