Please specify termination and packaging codes: MSS7331-104MLC Termination: L = RoHS compliant gold over nickel over phos bronze Special order: T = RoHS tin-silver-copper (95.5/4/0.5) over tin over nickel over phos bronze or S = non-RoHS tin-lead (63/37) over tin over nickel over phos bronze. Packaging: C= 7″ machine-ready reel EIA481 embossed plastic tape (350 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 EIA481 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 4284A LCR meter or equivalent. 3. For SRF >13 MHz, SRF measured using an Agilent/ HP 8753D network Analyzer or equivalent. For SRF <13 MHz, SRF measured using an Agilent/ HP 4192A or equivalent. 4. DC current at 25°C that causes the specified inductance drop from its value without current. Click for temperature derating information. 5. Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Click for temperature derating information. 6. Electrical specifications at 25°C.
