1. When ordering, please specify termination and packaging codes:
DO3314-333MLC
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 (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 (3500 parts per full reel).
2. Inductance tested at 100 kHz, 0.1 Vrms. 3. DCR measured on a micro-ohmmeter. 4. SRF measured using Agilent/HP 4191A or equivalent. 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.
