1. When ordering, please specify termination and packaging codes:  
1812LS-105XJRC  
2. Inductance at 2.5 MHz measured using an Agilent/HP 4286A and  
a Coilcraft SMD-A fixture with Coilcraft-provided correlation pieces.  
Inductance at 0.79 MHz measured using an Agilent/HP 4192A and  
Coilcraft SMD-B test fixture.  
3. Q read at test frequency directly on an Agilent/HP 4192A LF  
impedance analyzer and a Coilcraft SMD-B test fixture.  
4. SRF measured using an Agilent/HP 8753D network analyzer and a  
Coilcraft SMD-D test fixture.  
5. DCR measured on a Cambridge Technology micro-ohmmeter.  
6. 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.  
7. Electrical specifications at 25°C.  
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.  
Visit http://www.coilcraft.com/colrcode.cfm for part marking data.  
Termination: R = RoHS compliant matte tin over nickel over silver-  
platinum-glass frit.  
L = RoHS compliant silver-palladium-platinum-glass frit.  
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 per full reel). Quantities less than full reel  
available: in tape (not machine ready) or with leader  
and trailer ($25 charge).  
D = 13″ machine-ready reel. EIA-481 embossed plastic  
tape. Factory order only, not stocked (2200 per  
full reel).  
B = Less than full reel. In an effort to simplify our part  
numbering system, Coilcraft is eliminating the need  
for multiple packaging codes. When ordering, simply  
change the last letter of your part number from B to C.
