Document 990 -1 Square Air Core Inductors – 1111SQ • Excellent Q factors – 210 at 400 MHz! • Inductance values from 27 to 47 nH • Flat top and bottom for reliable pick and place and mechanical stability Terminations RoHS compliant tin-silver over copper Environmental RoHS compliant, halogen free Weight 34 – 50 mg Ambient temperature –40°C to +125°C with Irms current Maximum part temperature +145°C (ambient + temp rise). Storage temperature Component: –40°C to +145°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 600/7″ reel; 2500/13″ reel; Plastic tape: 12 mm wide, 0.35 mm thick, 8 mm pocket spacing, 3.05 mm pocket depth Recommended pick and place nozzle: OD: 0.054″; ID: 0.031″ PCB washing Tested to MIL-STD-202 Method 215 plus an additional aqueous wash.

When ordering, specify tolerance, termination and packaging codes: 1111SQ-47NJEC Tolerance:G=2% J = 5% (Table shows stock tolerances in bold.) Termination:E =RoHS compliant tin-silver (96.5/3.5) over copper. Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) over copper or S = non-RoHS tin-lead (63/37) over copper. 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 (2500 parts per full reel). Factory order only, not stocked. 2. Inductance measured at specified test frequency, 0.1 Vrms, 0 A using an Agilent/HP 4286A LCR meter or equivalent with a Coilcraft CCF1191C test fixture. 3. Q measured at specified test frequency, using an Agilent/HP 4291A impedance analyzer or equivalent. 4. SRF measured using an Agilent/HP 8753 network analyzer or equivalent with a Coilcraft CCF1143 test fixture. 5. Current that causes a 20°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings 6. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
