KA5038-BL	560	480	0.198	0.007	0.236	5.6	1 : 0.188	1 : 0.156	2.8	19 V, 3.5 A

1	Inductance measured at 50 kHz, 0.1 Vrms, 0 Adc
2	Ipk is peak primary current drawn at minimum input voltage.
3	DCR is with the primary windings connected in series and the secondary windings connected in parallel
4	Leakage inductance is for both windings of the primary and is measured with the secondary windings shorted.
5	Turns ratios are with the primary windings connected in series and the secondary windings connected in parallel.
6	Output is for the secondary. Aux winding output is 15.5 V, 20 mA.
7	Ambient temperature range:	–40°C to +85°C
8	Storage temperature range:	Component: –40°C to +85°C Packaging tray: –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.
