1. When ordering, please pecify packaging code:
GA3095-ALC
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (250 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 (1000 parts per full reel). Factory order only, not
stocked.
2. L and Q measured at 150 MHz, 0.1 Vrms, 0 A using an Agilent/HP
4291A impedance analyzer with an Agilent/HP 16193A test fixture.
3. SRF measured using an Agilent/HP 8722ES network analyzer and a
Coilcraft SMD-D test fixture.
4. DCR measured using a micro-ohmmeter.
5. Current that causes a 15°C temperature rise from 25°C ambient.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /
85% relative humidity)
Mean Time Between Failures (MTBF) 1 billion hours
Packaging 250/7″reel; 1000/13″ reel Plastic tape: 16 mm wide,
0.35 mm thick, 12 mm pocket spacing, 4.9 mm pocket depth
PCB washing Only pure water or alcohol recommended
