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.
