When ordering, please specify termination and packaging codes: 1812WBT1.5-4LC Termination: L = 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). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ( 25 charge). B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to C. 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 25C. Measurements are referenced to 50 Ohms. Refer to Doc 362 Soldering Surface Mount Components before soldering.
