1. When ordering, please specify
termination
and
packaging
codes:
0603PS-473KLC
Termination: L
= RoHS compliant silver-palladium-platinum-glass
frit. Special order:
T
= RoHS tin-silver-copper
(95.5/4/0.5) or
S
= non-RoHS tin-lead (63/37).
Packaging: C
= 7″ machine-ready reel. EIA-481 embossed plastic
tape (2000 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 (7500 parts per full reel).
2. Inductance measured at 100 kHz, 0.1 Vrms, using a Coilcraft SMD-A
fixture in an Agilent/HP 4263B LCR meter.
3. Q measured on an Agilent/HP 4291 with an Agilent/HP 16193 test
fixture.
4. DCR measured on a micro-ohmmeter and a Coilcraft CCF840 test
fixture.
5. SRF measured using an Agilent/HP 8753D network analyzer and a
Coilcraft SMD-D test fixture.
6. DC current at which the inductance drops 10% (typ) from its value
without current.
7. Current that causes a 40°C temperature rise from 25°C ambient.
8. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
