| 1 | When ordering, please specify tolerance and packaging codes: e.g. 1812PS-105JLC | |
| Tolerance: | J = 5%, K = 10% (Table above shows stock tolerances in bold.) | |
| Packaging:
|
C = 7"
machine-ready reel EIA RS-481 clear plastic tape (600 parts per full reel). B = Less than full reel In tape, not machine ready. To have a leader and trailer added ($25 charge), use code letter C instead. D = 13" reel, machine-ready EIA RS-481 clear plastic tape. Factory order only, not stocked (2200 parts per full reel). |
|
| 2 | Inductance measured at 100 kHz, 0.1 Vrms, using Coilcraft SMD-A fixture in Agilent/HP 4263B LCR meter or equivalent. | |
| 3 | Tolerances in bold are stocked for immediate shipment | |
| 4 | Q measured 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 SMD-D test fixture test fixture. Details | |
| 7 | Isat: DC current at which the inductance drops 10% (typ.) from its value without current. Details | |
| 8 | Irms: Current that causes a 40°C temperature rise from 25°C ambient. Details | |
| 9 | Ambient temperature range: |
–40°C to +105°C with Irms current. +105°C to +145°C with derated current Derating curve |
| 10 | Storage temperature range: | Component: –40°C to +145°C Tape and reel packaging: –40°C to +80°C |
| 11 | Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between. | |
| 12 | Electrical specifications at 25°C. | |
