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 for the primary, measured at 250 kHz, 0.7 Vrms, 0 Adc.

3. Peak primary current drawn at minimum input voltage.

4. DCR is with the windings connected in parallel.

Aux

5. Leakage inductance is for the primary winding with the secondary

windings shorted.

6. Turns ratio is with the primary and the secondary windings connected in

parallel.

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

the auxiliary winding is 12 V

The primary windings and the secondary

windings are to be connected in parallel

on the PC board.

8. Electrical specifications at 25°C.

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