tolerance3
1. When ordering, specify tolerance, termination and packaging codes:
1812CS-333XGLC
Tolerance: G=2% J = 5% (Table shows stock tolerances
in bold.)
Termination:L=RoHS compliant silver-palladium-platinum-glass frit.
E=Halogen free component. RoHS compliant silverpalladium-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. 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).
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.
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.
