1 When ordering, please specify termination and packaging codes: e.g. DFT4532-474BLC
  Termination: L = RoHS compliant matte tin over nickel over phos-bronze
Special order, add cost: S = non-RoHS tin-lead (63/37)
  Packaging: C = 7" reel, machine-ready 
EIA-481 embossed plastic tape (600 per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge)
D = 13" reel, machine-ready 
EIA-481 embossed plastic tape. Factory order only, not stocked (2000 per full reel).
2 Frequency at which the differential mode attenuation equals 3 dB
3 Inductance is for each winding, measured at test frequency using a Voltech AT3600 or equivalent.
4 Irms: Current that causes a 20°C temperature rise from 25°C ambient.
5 DCR is specified per winding at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
6 Ambient temperature range: −40°C to +85°C
7 Storage temperature range: Component: −40°C to +105°C
Packaging trays or tubes: −40°C to +80°C
8 Maximum part temperature: +105°C (ambient + temp rise);
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.
