1008AF (2520)

Ferrite Chip Inductors

Our 1008AF Series wirewound inductors feature ferrite core construction and heavy gauge wire for high current handling and broadband filtering. This series covers inductance values from 0.9 uH to 10 uH and comes in ±10% and ±5% tolerances on all values.

Inductance values from 0.9 µH to 10 µH
5% tolerance now standard
Higher current rating and lower DCR than our other 1008 series

Notes

When ordering, please specify tolerance, termination and packaging codes: e.g. 1008AF-103XJRC
Inductance measured at 2.5 MHz using Coilcraft SMD-A fixture in an Agilent/HP 4286A impedance analyzer with Coilcraft-provided correlation pieces.
Tolerances in bold are stocked for immediate shipment.
SRF measured using an Agilent/HP 8753D network analyzer with a Coilcraft SMD-D fixture.
Isat: DC current at 25°C that causes a 10% (typ) inductance drop from its value without current.
DCR measured on a Cambridge Technology Micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.

Tolerance:

J = 5% K = 10% (Table above shows stock tolerances in bold.)

Termination:

R = RoHS compliant. Matte Sn over Ni over Ag-Pt-glass frit terminations.

T = RoHS Sn/Ag/Cu (95.5/4.0/0.5) (Special order, added cost)
S = Not RoHS Sn/Pb (63/37) (Special order, added cost)

Packaging:

C = 7″ machine-ready reel. EIA-481 embossed plastic tape (2000 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (7500 parts per full reel).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to C.
