When ordering, please specify packaging code: NA5936-ALD Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic tape (800 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 50 MHz on an Agilent/HP 4191A Impedance Analyzer or equivalent with a Coilcraft SMD-A fixture and correlation. 3. Q tested at 50 MHz on an Agilent/HP 4291A Impedance Analyzer or equivalent with a Coilcraft SMD-A fixture and correlation. 4. SRF tested on the Agilent/HP 8753D and a Coilcraft CCF1248 test fixture. 5. DCR tested on the Keithley 580 Micro Ohmmeter. 6. Current that causes a 15°C temperature rise from 25°C ambient. 7. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering. Weight 0.42 – 0.59 g Terminations RoHS compliant tin-silver (96.5/3.5) over copper. Ambient temperature –40°C to +125°C with Irms current, +125°C to +140°C with derated current Storage temperature Component: –40°C to +140°C. Tape and reel packaging: –40°C to +80°C Resistance to soldering heat Max three 40 second reflows at +260°C, parts cooled to room temperature between cycles Temperature Coefficient of Inductance (TCL) +5 to +70 ppm/°C Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C / 85% relative humidity) Failures in Time (FIT) / Mean Time Between Failures (MTBF) One per billion hours / one billion hours, calculated per Telcordia SR-332 Packaging 800/13″ reel Plastic tape: 24 mm wide, 0.3 mm thick, 12 mm pocket spacing, 6.1 mm pocket depth PCB washing Tested with pure water or alcohol only.
