1. When ordering, please specify packaging code:

C1174-ALD

4. DCR for secondary is with windings connected in parallel.

5. Leakage inductance for the primary is with the secondary and drive

windings shorted; leakage inductance for the drive winding is with the

secondary windings shorted.

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

tape (200 per full reel).

6. Turns ratio is with both secondary windings connected in parallel.

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.

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

winding output is 10 V, 20 mA.

8. Electrical specifications at 25°C.

2. Inductance is for the primary, measured at 100 kHz, 0.1 Vrms.

3. Peak primary current drawn at minimum input voltage.

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