1. When ordering, please specify termination and packaging codes:
1812LS-105XJLC
Termination: L = RoHS compliant silver-palladium-platinum-glass frit.
Special order: T = RoHS tin-silver-copper (95.5/4/0.5)
or S = non-RoHS tin-lead (63/37).
Designer’s Kit C314 contains 10 of each value
Core material Ferrite
Terminations RoHS compliant silver-palladium-platinum-glass frit.
Other terminations available at additional cost.
Weight 142 – 171 mg
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
Ambient temperature –40°C to +85°C with Irms current, +85°C to
tape (600 per full reel).
+100°C with derated current
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. Factory order only, not stocked (2200 per full
reel).
Storage temperature Component: –40°C to +100°C.
Tape and reel packaging: –40°C to +80°C
Resistance to soldering heat Max three 40 second reflows at
+260°C, parts cooled to room temperature between cycles
Temperature Coefficient of Inductance (TCL) +200 to +700 ppm/°C
2. Inductance at 2.5 MHz measured using an Agilent/HP 4286A and
a Coilcraft SMD-A fixture with Coilcraft-provided correlation pieces.
Inductance at 0.79 MHz measured using an Agilent/HP 4192A and
Coilcraft SMD-B test fixture.
3. Q read at test frequency directly on an Agilent/HP 4192A LF imped-
ance analyzer and a Coilcraft SMD-B test fixture.
4. SRF measured using an Agilent/HP 8753D network analyzer and a
Coilcraft SMD-D test fixture.
5. DCR measured on a Cambridge Technology micro-ohmmeter.
Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /
85% relative humidity)
Failures in Time (FIT) / Mean Time Between Failures (MTBF)
One per billion hours / one billion hours, calculated per Telcordia SR-332
Packaging 600/7″ reel; 2200/13″ reel. Plastic tape: 12 mm wide,
0.3 mm thick, 8 mm pocket spacing, 3.7 mm pocket depth
PCB washing Tested with pure water or alcohol only. For other
solvents, see Doc787_PCB_Washing.pdf
6. Current that causes a 15°C temperature rise from 25°C ambient.
Because of their open construction, these parts will not saturate.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
