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.
