1. When ordering, specify tolerance, termination and packaging codes:
Designer’s Kit C337 contains 10 of each 5% part
Core material Ceramic
1812CS-333XGLC
Tolerance: G= 2% J = 5% (Table shows stock tolerances in bold.)
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).
Terminations RoHS compliant silver-palladium-platinum-glass frit.
Other terminations available at additional cost.
Weight 109 – 128 mg
Ambient temperature –40°C to +125°C with Irms current, +125°C
to +140°C with derated current
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (600 parts per full reel).
Storage temperature Component: –40°C to +140°C.
Packaging: –40°C to +80°C
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 parts per
full reel).
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
2. Inductance measured using a Coilcraft SMD-A fixture in an Agilent/HP
4286A impedance analyzer with Coilcraft-provided correlation pieces.
3. Tolerances in bold are stocked for immediate shipment.
4. Q measured using an Agilent/HP 4291A with an Agilent/HP 16193 test
fixture.
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
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.
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
PCB washing Only pure water or alcohol recommended
7. Current that causes a 15°C temperature rise from 25°C ambient.
8. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
Specifications subject to change without notice.
