Surface Mount 
Power Transformer

• Can be used with Linear Technology LT1725 Flyback Controller.
• Suitable for use in PoE applications.
• Ideal for use in telecommunications isolated converters and isolated power supplies
• 500 Vrms, one minute isolation between windings
• Six 1:1 windings

• A9967-AL_	10.0	9.0	0.045	0.200	2.3	15 V, 2 A

  1	When ordering, please specify packaging code: e.g. A9967-ALD
  	Packaging:	D = 13" machine-ready reel EIA 481 embossed plastic 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 per winding of the primary, measured at 100 kHz, 0.1 Vrms, 0 Adc. Inductance of the primary, with three windings connected in series is 90 μH.
  3	Peak primary current (with three windings connected in series) drawn at minimum input voltage. Peak current per winding is 7.0 A.
  4	DCR is per winding, measured at 25°C. For other operating temperatures, use this DCR at Temperaturecalculator.
  5	Leakage inductance is for one winding and is measured with all other windings shorted.
  6	Output is with both windings of the secondary connected in parallel.
  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.
