1. When ordering, please specify termination and packaging code:
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″ machine-ready reel. EIA-481 embossed plastic
tape (600 parts per full reel). Quantities less than full
reel available: in tape (not machine ready) or with
leader and trailer ($25 charge)
4
D =13″ machine-ready reel. EIA-481 embossed plastic
tape. Factory order only, not stocked (2000 parts 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.
Ø
4. Current that causes a 20°C temperature rise from 25°C ambient.
5. DCR is specified per winding.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
