features
• Virtually eliminates channel capacitance,
a primary cause of reduced system performance
• Eases routing design of DDR SDRAM termination
• High precision 1% is standard
• Saves board space and high density mounting
• Marking: Black body color with white marking (cut-out)
• Products with lead-free terminations meet EU RoHS
requirements. Pb located in glass material, electrode
and resistor element is exempt per Annex 1, exemption
5 of EU directive 2005/95/EC
