Please specify termination and packaging codes: MSS1260-184KLD Termination: L =RoHS compliant matte tin over nickel over phos bronze. Special order: T = RoHStin-silver-copper(95.5/4/0.5) or S = non-RoHS tin-lead (63/37). Packaging: D=13″ 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 D instead. 2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP 4263B LCR meter or equivalent. 3. DCR measured on a micro-ohmmeter and a Coilcraft CCF858 test fixture. 4. SRF measured using Agilent/HP 4191A or equivalent. 5. DC current at which the inductance drops the specified amount from its value without current. 6. Current that causes the specified temperature rise from 25°C ambient. 7. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
