1. Please specify tolerance, termination and packaging codes:
0908SQ-27N
GLC
Tolerance:
G = 2%, J =5% (Table shows stock tolerances in bold.)
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 or equivalent with a Coilcraft SMD-A test
fixture and Coilcraft-provided correlation pieces.
3. Tolerances in bold are stocked for immediate shipment.
4. Q measured at 400 MHz using an Agilent/HP 4291A impedance
analyzer or equivalent.
5. SRF measured using an Agilent/HP 8753 network analyzer and a
Coilcraft SMD-D test fixture.
6. Current that causes a 20°C temperature rise from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
