1. When ordering, specify
tolerance, termination
and
packaging
codes:
1515SQ-82NJEC
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.
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.
Tolerance:
2. Inductance measured at specified test frequency, 0.1 Vrms, 0 A using
an Agilent/HP 4287A LCR meter with the following Coilcraft test fixtures:
CCF1191C for 1515SQ; CCF1197A for 2222SQ and 2929SQ.
3. Tolerances in bold are stocked for immediate shipment.
4. Q measured at specified test frequency, using an Agilent/HP 4291A
impedance analyzer.
5. SRF measured using an Agilent/HP 8753 network analyzer and the
following Coilcraft test fixtures: CCF1143 for 1515SQ; CCF1199
for 2222SQ-90N and 2222SQ-161; CCF1200 for 2222SQ-301 and
2929SQ-501.
6. Current that causes a 20°C temperature rise from 25°C ambient. This
information is for reference only and does not represent absolute
maximum ratings.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
