SPECIFICATIONS


DA2099-AL_ 1 : 1 3.79 13.0 2.30 2.85 221 13.0
1 When ordering, please specify packaging code: e.g. DA2099-ALD
Packaging: D = 13" reel, machine-ready 
EIA-481 embossed plastic tape (500 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 at 100 kHz, 0.3 Vrms, 0 Adc
3 Leakage inductance measured at 100 kHz, 0.3 Vrms with secondary pins shorted.
4 DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
5 Based on Bsat of the core at 25°C and number of turns of the primary.
6 Capacitance measured at 100 kHz, 0.3 Vrms
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.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested with pure water or alcohol only. Other solvents
