1. When ordering, specify

tolerance, termination

and

packaging

codes:

1812SMS-R12GLC

Tolerance: G

= 2%

= 5%

Termination: L

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

Special order:

= RoHS tin-silver-copper

(95.5/4/0.5) or

= non-RoHS tin-lead (63/37).

Packaging: C

= 7″ machine-ready reel. EIA-481 embossed plastic

tape, 500 parts per full reel.

= Less than full reel. In tape, but not machine-ready.

To have a leader and trailer added ($25 charge),

use code letter C instead.

= 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.
