When ordering, please specify termination and packaging codes: LPO4812-473MLC Termination: L = RoHS compliant silver-palladium-platinum-glass frit 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 (1000 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 (3500 parts per full reel). 2. Inductance tested at 100 kHz, 0.1 Vrms 0 Adc. 3. DC current at which the inductance drops 10% (typ) from its value without current. 4. Current that causes a 40°C temperature rise from 25°C ambient. 5. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
