1. When ordering, specify tolerance, terminations and packaging codes:
1812PS-105JRC
J = 5% K = 10%(Table shows stock tolerances in bold.)
Terminations: R = Halogen free component. Matte tin over nickel oversilver-platinum-glass frit terminations.
L = RoHS compliant, not halogen-free. Silver-palladiumplatinum-glass frit terminations
Packaging:C = 7″ machine-ready reel. EIA-481 embossed plastic tape(600 parts per full reel). Quantities less than full reelavailable: in tape (not machine ready) or with leaderand trailer ($25 charge).
D = 13″ machine-ready reel. EIA-481 embossed plastictape. Factory order only, not stocked (2200 parts perfull reel)
Tolerance:

B = Less than full reel. In an effort to simplify our partnumbering system, Coilcraft is eliminating the needfor multiple packaging codes. When ordering, simply
change the last letter of your part number from B to C.
2. Inductance measured at 100 kHz, 0.1 Vrms, using aCoilcraft SMD-A fixture
in an Agilent/HP 4263B LCR meter.
3. Tolerances in bold are stocked for immediate shipment.
4. Q measured at 1 MHz on an Agilent/HP 4291 with an Agilent/HP 16193 testfixture.
5. DCR measured on micro-ohmmeter and a Coilcraft CCF840 test fixture.
6. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft
SMD‑D test fixture.
7. DC current at 25°C that causes an inductance drop of 10% (typ) from its
value without current. Click for temperature derating information.
8. Current that causes the a 40°C temperature rise from 25°C ambient. Thisinformation is for reference only and does not represent absolute maximum
ratings. Click for temperature derating information.
9. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
