When ordering, specify tolerance, termination and packaging codes: 1812CS-333XGLC Tolerance: G = 2% J = 5% (Table shows stock tolerances in bold.) Termination: L = RoHS compliant silver-palladium-platinum-glass frit. Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). Packaging: C = 7 machine-ready reel. EIA-481 embossed plastic tape (600 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. Factory order only, not stocked (2200 parts per full reel). 2. Inductance measured using a Coilcraft SMD-A fixture in an Agilent/HP 4286A impedance analyzer with Coilcraft-provided correlation pieces. 3. Tolerances in bold are stocked for immediate shipment. 4. Q measured using an Agilent/HP 4291A with an Agilent/HP 16193 test fixture. 5. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture. 6. DCR measured on a Cambridge Technology micro-ohmmeter and a Coilcraft CCF859 test fixture. 7. Current that causes a 15C temperature rise from 25C ambient. 8. Electrical specifications at 25C. Refer to Doc 362 "Soldering Surface Mount Components" before soldering. Designer's Kit C337 contains 10 of each 5% part Core material Ceramic Terminations RoHS compliant silver-palladium-platinum-glass frit. Other terminations available at additional cost. Weight 109 - 128 mg Ambient temperature -40C to +125C with Irms current, +125C to +140C with derated current Storage temperature Component: -40C to +140C.
