C1586-ALD

Packaging: D

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

tape (175 parts per full reel).

= Less than full reel. In tape, but not machine ready. To

have a leader and trailer added ($25 charge), use

code letter D instead.

Dot above pin1

Inductance is for the primary, measured at 250 kHz, 0.2 Vrms, 0 Adc.

Ipk

is peak primary current drawn at minimum input voltage.

DCR for the secondary is per winding.

Leakage inductance measured between pins 3 and 4 with all other pins

shorted.

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

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

winding output is 12 V, 20 mA.

8. Electrical specifications at 25°C.

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