1 When ordering, please specify packaging codes: e.g. M2022-ALC, M2022-ALPLC,  or M2022-ASLC.
  Packaging: C = 7" machine-ready reel
EIA-481 embossed plastic tape (600 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 C instead.
D = 13" reel, machine-ready 
EIA-481 embossed plastic tape. Factory order only, not stocked (2200 per full reel).
2 Frequency at which the differential mode attenuation equals 3 dB
3 Inductance is per winding, measured at 10 MHz.
4 DCR is per winding, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
5 Winding to winding isolation (hipot) tested for one minute.
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.
