Please specify termination and packaging codes: MSS6122-104MLC Termination: L = RoHS compliant gold over nickel over phos bronze 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 (500 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 (1500 per reel per full reel). 2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP 4263B LCR meter or equivalent. 3. SRF measured using an Agilent/HP 4191A or equilvalent. 4. DC current at which the inductance drops the specified amount 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. Specifications subject to change without notice.
