1 When ordering, please specify termination and packaging codes: e.g. 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 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 tested between pins 4 and 3 at 500 kHz, 0.5 Vrms, 0 Adc.
3 DCR is per winding at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 Leakage inductance is for the primary with both windings connected in series and with the secondary windings shorted.
5 Volt-time product 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 Ambient temperature range: −40°C to +125°C
8 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
9 Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
10 Electrical specifications at 25°C.
