Please specify tolerance, termination and packaging codes: DO1608C-105MLC Tolerance: K=10%, M = 20% (Table shows stock tolerances in bold.) 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. Tolerances in bold are stocked for immediate shipment 4. DC current at which the inductance drops 10% (typ) from its value without current. 5. Current that causes the specified temperature rise from 25°C ambient. 6. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
