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. EU RoHS regulation is not intended for
Pb-glass contained in electrode, resistor element and glass.
