1008LS (2520) Series

Wirewound Ferrite Beads

Our 1008LS Series wirewound ferrite beads have a ferrite core construction that achieves high current handing and low DCR. Impedance ranges from 64 Ohms to 7500 Ohms at 10 MHz, and the tight inductance tolerance of ±5% is standard, stocked, and ready for shipment.

Higher performance than other surface mount ferrite beads in the market
High impedance across a wide bandwidth
Ferrite construction and heavy gauge wire for high current handling
Extremely low DCR for high current applications
Eliminates high frequency noise in power supplies or RF signal isolation applications
Defense Supply Center CID A-A-59698
AEC-Q200 Grade 3 (−40°C to +85°C)

Notes

When ordering, please specify termination and packaging codes: e.g. 1008LS-103XJRC
Inductance measured at 7.9 MHz using a Coilcraft SMD-A fixture in an Agilent/HP 4286A impedance analyzer with Coilcraft-provided correlation pieces.
SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture.
DCR measured at 25°C on a Cambridge Technology Micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
Irms: 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. Because of their open construction, these parts will not saturate.
Current production parts are marked with one dot. Prior production parts were marked with three dots. Single color dots are not unique identifiers and correspond to multiple inductance values. Part marking does not indicate polarity.

Termination:

R = RoHS compliant, matte tin over nickel over silver platinum-glass frit.
E = Halogen free component. RoHS compliant. Silver-palladium-platinum-glass frit terminations.
L = RoHS compliant, not halogen-free. Silver-palladium-platinum-glass frit.
T = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
S = non-RoHS tin-lead (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.
