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.
