This surface mount flyback transformer is designed for

use with National Semiconductor LM5000 DC/DC regu-

lator. The core completely encloses the windings to

minimize EMI interference. The transformer features

very low DCR, 500 V isolation and a leakage inductance

Part number

1. When ordering, please specify a packaging code:

2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc.

3. Leakage inductance measured at 100 kHz, 0.1 Vrms from pins 1 to 4

4. Isolation measured from pin 1 to pins 5 and 6; from 2 to 5 and 6; and

5. Electrical specifications at 25°C.

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