1812LS (4532) Series

Wirewound Ferrite Beads

Our 1812LS Series wirewound ferrite beads have a ferrite core construction that achieves high current handing and low DCR. Impedance ranges from 770 Ohms to 191 kOhms 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-59699

Hinweise

When ordering, please specify termination and packaging codes: e.g. 1812LS-105XJRC
Inductance at 2.5 MHz measured using a Coilcraft SMD-A fixture in an Agilent/HP 4286A impedance analyzer with Coilcraft-provided correlation pieces. Inductance at 0.79 MHz measured using a Coilcraft SMD-B fixture in an Agilent/HP 4192A 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 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.

Anschlüsse:

R = RoHS compliant, matte tin over nickel over silver platinum-glass frit.
L = RoHS compliant 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)

Verpackung:

C = 7″ machine-ready reel. EIA-481 embossed plastic tape (600 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 (2200 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.
