1. When ordering, specify
tolerance, termination
and
packaging
codes:
1111SQ-47NJEC
Tolerance: G
= 2%
J
= 5%
(Table shows stock tolerances in bold.)
Termination: E
= RoHS compliant tin-silver (96.5/3.5) over copper.
Special order, added cost:
T
= RoHS tin-silver-copper (95.5/4/0.5) over copper or
S
= non-RoHS tin-lead (63/37) over copper.
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 (2500 parts per full reel). Factory order only, not stocked.
2. Inductance measured at specified test frequency, 0.1 Vrms, 0 A using an Agilent/HP 4286A LCR meter or equivalent with a Coilcraft CCF1191C test
fixture.
3. Q measured at specified test frequency, using an Agilent/HP 4291A impedance analyzer or equivalent.
4. SRF measured using an Agilent/HP 8753 network analyzer or equivalent with a Coilcraft CCF1143 test fixture.
5. Current that causes a 20°C temperature rise from 25°C ambient.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
