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 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. 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.

8. Electrical specifications at 25°C.

Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
