1. 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.
