When ordering, specify tolerance, termination and packaging codes: DO3316H-472MLD Tolerance: M = 20%, K = 10% (Table shows stock tolerances in bold.) Termination: L = RoHS compliant tin-silver-copper over copper. Special order: S = non-RoHS tin-lead (63/37). Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic tape (750 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. 2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP 4263B LCR meter or equivalent. 3. Tolerances in bold are stocked for immediate shipment. 4. SRF measured using Agilent/HP 8753D network analyzer. 5. DC current at which the inductance drops 10% (typ) from its value without current. 6. Current that causes a 40°C temperature rise from 25°C ambient. 7. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
