1. When ordering, specify

tolerance, termination and packaging codes:

1812SMS-R12GLC

Tolerance:

G = 2% J = 5%

Termination: L = RoHS compliant tin-silver (96.5/3.5) over copper.

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, 500 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, 2000 parts per

full reel.

2. Inductance tested at 150 MHz on an Agilent/HP 4286A LCR meter or

equivalent with a Coilcraft SMD-A test fixture and correlation.

3. Tolerances in bold are stocked for immediate shipment.

4. Q tested at 150 MHz on an Agilent/HP 4291A Impedance Analyzer with

an Agilent/HP 16193 test fixture or equivalents.

5. SRF tested on the Agilent/HP 8753D Network Analyzer or equivalent

and a Coilcraft CCF1248 test fixture.

6. DCR tested on the Cambridge Technology Model 510 Micro-ohmmeter

or equivalent.

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.
