Please specify termination and packaging codes: MSS5121-394MLC 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 (600 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. Factory order only, not stocked (2500 parts per full reel). 2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using Coilcraft SMD-A fixture in an Agilent/HP 4284A impedance analyzer. 3. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture. 4. DC current at which the inductance drops the specified amount from its value without current. 5. Current that causes the specified temperature rise for 25C ambient. 6. Electrical specifications at 25C. Refer to Doc 362 "Soldering Surface Mount Components" before soldering.
