1812LS Ferrite Chip Inductors
for xDSL Filters

New RoHS part numbers are shown. Cadmium was removed from terminations. The next to the last character is now L to indicate RoHS compliance. Also, 10% tolerance (K) is no longer offered. (View old data sheet.)

Wirewound design for high Q and low DC resistance
Ferrite construction for higher current carrying capacity
Inductance values from 12 µH to 180 µH (tolerances as low as 5%)
RoHS-compliant 260°C compatible. Silver-palladium-platinum-glass frit terminations.
Samples of all values are available in Coilcraft Designer's Kit C314

1	When ordering, please specify packaging codes: e.g. 1812LS-105XJLC

Packaging:

C = 7" machine-ready reel
EIA-481 embossed plastic tape (600 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" reel, machine-ready
EIA-481 embossed plastic tape. Factory order only, not stocked (2200 parts per full reel).

2	Inductance at 2.5 MHz measured using Coilcraft SMD-A fixture in Agilent/HP 4286A impedance analyzer with Coilcraft-provided correlation pieces. Inductance at 0.79 MHz measured using Coilcraft SMD-B fixture in Agilent/HP 4192A impedance analyzer with Coilcraft-provided correlation pieces.
3	Q read directly on Agilent/HP 4192A LF impedance analyzer and Coilcraft SMD-B fixture using Coilcraft-provided correlation pieces.
4	SRF measured using Agilent/HP 8753D network analyzer and Coilcraft SMD-D test fixture.
5	DCR measured on Cambridge Technology Micro-ohmmeter.
6	Irms: Average current for 15°C temperature rise from 25°C ambient.
7	Ambient temperature range:	–40°C to +85°C with Irms current. +85°C to +100°C with derated current. Derating curve
8	Storage temperature range:	Component: –40°C to +100°C Packaging: –55°C to +80°C
9	Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
10	Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
