When ordering, specify tolerance, termination and packaging codes: 1515SQ-82NJEC 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. 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. Designer’s Kit C438 contains 10 each of all 5% parts Terminations RoHS compliant tin-silver over copper 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) Mean Time Between Failures (MTBF) 1 billion hours PCB washing Tested to MIL-STD-202 Method 215 plus an additional aqueous wash.

  • Excellent Q factors – up to 230 at 400 MHz!
  • Current handling as high as 5.7 Amps
  • Inductance values from 47 to 500 nH
  • Flat top and bottom for reliable pick and place and mechanical stability 1515SQ 2222SQ 2929SQ 2. Inductance measured at specified test frequency, 0.1 Vrms, 0 A using an Agilent/HP 4287A LCR meter with the following Coilcraft test fixtures: CCF1191C for 1515SQ; CCF1197A for 2222SQ and 2929SQ. 3. Tolerances in bold are stocked for immediate shipment. 4. Q measured at specified test frequency, using an Agilent/HP 4291A impedance analyzer. 5. SRF measured using an Agilent/HP 8753 network analyzer and the following Coilcraft test fixtures: CCF1143 for 1515SQ; CCF1199 for 2222SQ-90N and 2222SQ-161; CCF1200 for 2222SQ-301 and 2929SQ-501. 6. 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. 7. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
