Please specify tolerance, termination and packaging codes: 0908SQ-27NGLC 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.
