1. When ordering, please specify a packaging code:

B0863-BLD

Primary

Secondary

Packaging: D = 13″ machine ready reel. EIA-481 embossed plastic tape (200 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 at 10 kHz, 0.1 Vrms, 0 Adc.

3. DCR for the secondary is measured with the windings connected in parallel.

4. Leakage inductance is for the primary and is measured with all other windings shorted.

5. Turns ratio is with the secondary windings connected in parallel.

6. Isolation is measured from the primary, reset and bias windings to the secondary and drive windings.

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

Reset

Drive

Bias

8. Electrical specifications at 25°C.

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

Secondary windings to be connected in

parallel on PC board.

Specifications subject to change without notice.
