1. When ordering, please specify a packaging code:

4. DCR for the primary and the secondary is measured with windings

connected in parallel.

5. Leakage inductance is for the primary, measured with the windings

connected in parallel and the secondary windings shorted.

6. Turns ratio is with the primary windings and secondary windings con-

nected in parallel.

7. Output is with the secondary windings connected in parallel. Output of the

drive winding is 6 V, 10 mA. Output of the bias winding is 11.2 V, 20 mA.

8. Electrical speciﬁcations at 25°C.

JA4387-ALD

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

tape (175 parts 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 measured at 250 kHz, 0.1 Vrms, 0 Adc.

3. Peak primary current drawn at minimum input voltage.

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