## 1. When ordering, specify **tolerance** , **terminations** and **packaging** codes: 

**1812PS-105JLC Tolerance: J** = 5% **K** = 10% (Table shows stock tolerances in bold.) **Terminations: L** = RoHS compliant, not halogen-free. Silver-palladiumplatinum-glass frit terminations **R** = Halogen free component. Matte tin over nickel over silver-platinum-glass frit terminations. **Packaging: C** = 7″ machine-ready reel. EIA-481 embossed plastic tape (600 parts 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 parts 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. 

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 test fixture. 

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. This information is for reference only and does not represent absolute maximum ratings. Click for temperature derating information. 

9. Electrical specifications at 25°C.
