Termination: L
= 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.
2. Inductance measured at 400 MHz, 0.1 Vrms, 0 A using an Agilent/
HP 4287A LCR meter with an Agilent/HP 16193A test fixture.
3. Q measured at 400 MHz using an Agilent/HP 4291A impedance
analyzer.
4. SRF measured using an Agilent/HP 8753 network analyzer and a
Coilcraft SMD-D test fixture.
5. Current that causes a 20°C temperature rise from 25°C ambient.
6. Electrical specifications at 25°C.
See Qualification Standards section for environmental and test data.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
These parts are preproduction products for electrical evaluation
only. Specification subject to change without notice.
