When ordering, specify tolerance, termination and packaging codes: 1008HT-R56TJLC Tolerance: F =1% G = 2% J = 5% (Table shows stock tolerances in bold.) Termination:L=RoHS compliant silver-palladium-platinum-glass frit. Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). Packaging:C =7″ machine-ready reel. EIA-481 embossed plastic tape (2000 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 (7500 parts per full reel). 2. Inductance measured using a Coilcraft SMD-A fixture in an Agilent/ HP 4286A impedance analyzer with Coilcraft-provided correlation pieces. 3. Tolerances in bold are stocked for immediate shipment. 4. Q measured using an Agilent/HP 4291A with an Agilent/HP 16193 test fixture. 5. SRF measured using an Agilent/HP 8720D network analyzer and a Coilcraft SMD‑D test fixture. 6. DCR measured on a Cambridge Technology micro-ohmmeter and a Coilcraft CCF840 test fixture. 7. Current that causes a 15°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. 8. Electrical specifications at 25°C. See Color Coding section for part marking data.
