• Magnetically shielded chip inductors
• Provides high performance in transmit and receive filters
• 29 inductance values from 1.0 – 1000 µH
Core material Ceramic/Ferrite
Terminations RoHS compliant silver-palladium-platinum-glass frit.
Other terminations available at additional cost.
Weight 0.33 – 0.36 g
Ambient temperature –40°C to +85°C with Irms current, +85°C to
+125°C with derated current
Storage temperature Component: –40°C to +125°C.
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
Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /
85% relative humidity)
Failures in Time (FIT) / Mean Time Between Failures (MTBF)
38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332
Packaging 600/7″ reel; 2200/13″ reel. Plastic tape: 12 mm wide,
0.25 mm thick, 8 mm pocket spacing, 3.9 mm pocket depth
PCB washing Only pure water or alcohol recommended
1. When ordering, specify tolerance, termination and packaging codes:
1812FS-105JLC
Tolerance: J = 5% K = 10%
(Table shows stock tolerances in bold.)
Termination: L = Silver-palladium-platinum-glass frit terminations
Special order: T = RoHS tin-silver-copper (95.5/4/0.5)
or S = non-RoHS tin-lead (63/37).
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (600 parts per full reel).
B = Less than full reel. On tape, but not machine ready.
To have a leader and a trailer added ($25 charge),
use code letter C instead.
D = 13″ machine-ready reel. EIA-481 embossed plastic
tape (2200 parts per full reel).
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft
SMD-A fixture in an Agilent/HP 4263B impedance analyzer.
3. Tolerances in bold are stocked for immediate shipment.
4. Q measured at 1 MHz on an Agilent/HP 4291A with an Agilent/HP 16193
test fixture.
5. DCR measured on a micro-ohmmeter and a Coilcraft CCF840 test
fixture.
6. SRF measured using an Agilent/HP 8753D network analyzer and a
Coilcraft SMD-D test fixture.
7. DC current at which the inductance drops 10% (typ) from its value
without current.
8. Current that causes a 40°C temperature rise from 25°C ambient.
9. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
Specifications subject to change without notice.
