When ordering, please specify termination and packaging code: JA4220-ALC Termination: L =RoHS compliant tin-silver-copper over silver-platinum-glass frit. Special order: S = non-RoHS tin-lead (63/37). Packaging:C =7″ 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. D =13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (3000 parts per full reel). 2. Inductance measured at 100 kHz, 0.1 V, 0 Adc on an Agilent/HP 4192 or equivalent. 3. DCR measured on a micro-ohmmeter. 4. Electrical specifications at 25°C. Measurements are referenced to 50 Ohms. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
