When ordering, please specify termination and packaging codes: LPO3310-473MLC 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 using an Agilent/HP 4192A. 3. DCR measured on a micro-ohmmeter. 4. SRF measured using Agilent/HP 8753ES or equivalent. 5. DC current at which the inductance drops 10% (typ) from its value without current. 6. Current that causes a 25°C temperature rise from 25°C ambient. 7. Electrical specifications at 25°C.
