1. When ordering, specify tolerance, termination and packaging codes:
1812CS-333XGEC
Designer’s Kit C337 contains 10 of each 5% part
Core material Ceramic
Environmental RoHS compliant, halogen free
Tolerance: G= 2% J = 5%
(Table shows stock tolerances in bold.)
Terminations Silver-palladium-platinum-glass frit. Other terminations
available at additional cost.
Termination: E = Halogen free component. RoHS compliant silver-
palladium-platinum-glass frit terminations.
L = RoHS compliant, not halogen-free. Silver-palladium-
platinum-glass frit terminations.
Weight 109 – 128 mg
Ambient temperature –40°C to +125°C with Irms current
Maximum part temperature +140°C (ambient + temp rise).
R = RoHS compliant matte tin over nickel over silver-
platinum-glass frit.
Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37).
Storage temperature Component: –40°C to +140°C.
Tape and reel packaging: –40°C to +80°C
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (600 parts per full reel). Quantities less than full
reel available: in tape (not machine ready) or with
leader and trailer ($25 charge).
Resistance to soldering heat Max three 40 second reflows at
+260°C, parts cooled to room temperature between cycles
Temperature Coefficient of Inductance (TCL) +25 to +125 ppm/°C
D = 13″ machine-ready reel. EIA-481 embossed plastic
tape. Factory order only, not stocked (2200 parts per
full reel).
Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /
85% relative humidity)
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.
2. Inductance measured using a Coilcraft SMD-A fixture in an Agilent/HP
4286A impedance analyzer with Coilcraft-provided correlation pieces.
Failures in Time (FIT) / Mean Time Between Failures (MTBF)
One per billion hours / one billion hours, calculated per Telcordia SR-332
Packaging 600 per 7″ reel; 2200 per 13″ reel. Plastic tape: 12 mm wide,
0.3 mm thick, 8 mm pocket spacing, 3.7 mm pocket depth
3. Tolerances in bold are stocked for immediate shipment.
4. Q measured using an Agilent/HP 4291A with an Agilent/HP 16193 test
fixture.
PCB washing Tested to MIL-STD-202 Method 215 plus an additional
aqueous wash. See Doc787_PCB_Washing.pdf.
5. SRF measured using an Agilent/HP 8753D network analyzer and a
Coilcraft SMD-D test fixture.
6. DCR measured on a Cambridge Technology micro-ohmmeter and a
Coilcraft CCF859 test fixture.
7. 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.
8. Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
