1 When ordering, please specify packaging code: e.g. A0009-ALD
Packaging: D = 13" machine-ready reel
EIA 481 embossed plastic tape (150 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 measured across input and auxiliary windings at 100 kHz, 0.1 Vrms, 0 Adc for one minute.
3 DCR measured at 25°C. For other operating temperatures,use this DCR at Temperature calculator.
4 Leakage inductance measured at 100 kHz, 0.1 Vrms from pins 1 to 4 with all other pins shorted.
5 Isolation measured from pin 1 and 2 to pins 5 and 6; and from pins 1, 2, 5 and 6 to the core.
6 Ambient temperature range: −40°C to +85°C
7 Storage temperature range: Component: −40°C to +85°C
Tape and reel packaging: −40°C to +80°C
8 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.
9 Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info
