1. When ordering, please specify

termination and packaging codes:

MA5632-ALD

Termination: L = RoHS compliant tin-silver over tin over nickel over

phos bronze.

Special order: T = RoHS tin-silver-copper

(95.5/4/0.5) or

S = non-RoHS tin-lead (63/37).

Packaging:

D = 13

″ machine ready reel. EIA-481 embossed plastic

tape (600 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 tested between pins 4 and 3 at 500 kHz, 0.5 Vrms, 0 Adc.

3. DCR is per winding.

4. Leakage inductance is for the primary with both windings connected in

series and with the secondary windings shorted.

5. Based on Bsat of the core at 25°C and number of turns on winding 4-3.

6. Calculated output power based on 150 kHz operating frequency.

Power varies depending on application.

7. Electrical specifications at 25°C.

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