1 When ordering, please specify packaging code: e.g. RA6870-ALC
  Packaging: C = 7" machine-ready reel
EIA 481 embossed plastic tape (2000 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.
D = 13" machine-ready reel
EIA 481 embossed plastic tape (7500 parts per full reel).
2 Frequency at which the differential mode attenuation equals 3 dB
3 Inductance is for the primary, measured at 100 MHz.
4 DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
5 Isolation (hipot) measured for one minute.
6 Irms: Current per winding that causes a 20°C rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
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 to MIL-STD-202 Method 215 plus an additional aqueous wash. More info
