1When ordering, please specify packaging code: e.g. B0695-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 for the primary, measured at 10 kHz, 0.1 Vrms, 0 Adc
3 Ipk is the peak primary current drawn at minimum input voltage
4 DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
5 Leakage inductance measured between pins 4 and 6 with all other pins shorted.
6 Turns ratio is with the secondary windings connected in parallel.
7 Capacitance measured between pins 3 and 4 with all other pins shorted.
8 Isolation is measured from the primary and bias windings to the secondary.
9 Ambient temperature range: –40°C to +85°C
10Storage temperature range: Component: −40°C to +85°C
Tape and reel packaging: −40°C to +80°C
11 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.
12Electrical 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
