Document 102-1 Chip Inductors – 1008CT Series (2520) The 0.055″ profile makes these parts ideal for low clearance applications. Their simple construction ensures high reliability and stability, and they feature much Part number1 1008CT-040X_L_ 1008CT-080X_L_ 1008CT-100X_L_ 1008CT-150X_L_ 1008CT-200X_L_ 1008CT-300X_L_ 1008CT-400X_L_ 1008CT-500X_L_ 1008CT-600X_L_ 1008CT-700X_L_ 1008CT-800X_L_ 1008CT-900X_L_ 1008CT-101X_L_ Inductance2 (nH) 4.7 @ 50 MHz 8.2 @ 50 MHz 10 @ 50 MHz 15 @ 50 MHz 20 @ 50 MHz 30 @ 50 MHz 40 @ 50 MHz 50 @ 50 MHz 60 @ 50 MHz 70 @ 50 MHz 80 @ 50 MHz 90 @ 50 MHz 100 @ 50 MHz Percent3 tolerance 5 5,2 5 5,2 5,2 5,2 5,2 5,2 5,2,1 5,2,1 5,2,1 5,2 5,2 1. When ordering, specify tolerance, termination and packaging codes: 1008CT-101XJLC 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 at 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. 8. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering. Tolerance: higher SRF values than ferrite alternatives.
