1. When ordering, specify **tolerance** and **packaging** codes: ~~-—_____~~ | **1812PS-105JLC** 

**Tolerance: J** = 5% **K** = 10% 

(Table shows stock tolerances in bold.) 

**Packaging: C** = 7″ machine-ready reel. EIA-481 embossed plastic tape (600 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 (2200 parts per full reel). 

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 which the inductance drops 10% (typ) from its value without current. 

8. Current that causes a 40°C temperature rise from 25°C ambient. 

9. Electrical specifications at 25°C.
