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_B_ 1008CT-080X_B_ 1008CT-100X_B_ 1008CT-150X_B_ 1008CT-200X_B_ 1008CT-300X_B_ 1008CT-400X_B_ 1008CT-500X_B_ 1008CT-600X_B_ 1008CT-700X_B_ 1008CT-800X_B_ 1008CT-900X_B_ 1008CT-101X_B_ 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, please specify tolerance and packaging codes: 1008CT-101XJBC Tolerance: F = 1% G = 2% J = 5% (Table shows stock tolerances in bold.) 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). higher SRF values than ferrite alternatives.
