When ordering, please specify termination and packaging codes: DO1608C-105MLC 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 (750 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 (2500 parts per full reel). 2. Tested at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP 4263B LCR meter or equivalent. 3. DC current at which the inductance drops 10% (typ) from its value without current. 4. Current that causes a 15°C temperature rise from 25°C ambient. 5. Electrical specifications at 25°C.
