When ordering, please specify termination and packaging codes: SER1410-202MED Termination: E = RoHS compliant tin-silver over copper. Special order: T = RoHS tin-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. 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 measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4263B LCR meter or equivalent. 3. DCR measured on a Keithley 580 micro-ohmmeter or equivalent. 4. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture. 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.
