1. When ordering, specify tolerance, termination and packaging codes:
2. Inductance and Q tested on the Agilent/HP 4291A with the 16193 fixture
and correlation.
1812SMS-R12GLC
Tolerance: G = 2% J = 5%
3. Tolerances in bold are stocked for immediate shipment.
4. SRF tested on the Agilent/HP 8753D and the SMD-D test fixture.
5. DCR tested on the Cambridge Technology Model 510 Micro-ohmmeter.
6. Current that causes a 15°C temperature rise from 25°C ambient.
7. Electrical specifications at 25°C.
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
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
For part marking data see Color Coding section.
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.
