When ordering, please specify termination and packaging codes: SLC7530S-101MLC Termination: L = RoHS compliant matte tin over nickel over copper 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 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 (1700 parts per full reel). 2. Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4263B LCR meter or equivalent. 3. DCR is measured on a micro-ohmmeter at points indicated in the diagram. Points used for measuring DCR 4. SRF measured using an Agilent/HP 8753ES network analyzer and a Coilcraft SMD-D fixture. 5. DC current at which the inductance drops 20% (typ) from its value without current. 6. Current that causes a 40°C rise from 25°C ambient. 7. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
