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.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
