Please specify termination and packaging codes: LPS4414-223MLC Termination: L = RoHS compliant silver-palladiumplatinum-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 (1000 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 (3500 parts per full reel). 2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc. 3. DCR measured on a micro-ohmmeter. 4. SRF measured using Agilent/HP 8753ES or equivalent. 5. DC current at which the inductance drops the specified amount from its value without current. 6. Current that causes the specified temperature rise from 25°C ambient. 7. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
