When ordering, please specify termination and packaging codes: 1812WBT1.5-4LC Termination:E =RoHS compliant gold over nickel over moly-manganese Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). Packaging:C =7″ machine-ready reel. EIA-481 embossed plastic tape (600 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 C instead. D =13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (2200 parts per full reel). 2. Inductance is per winding 3. Electrical specifications at 25°C. Measurements are referenced to 50 Ohms. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
