•
High Density Packaging
Up to 30% less space per resistor than 0603 chip resistors
Up to 75% less space per resistor than 0805 chip resistors
Placement Efficiency
Networks require fewer placements than discrete components
Larger overall size eases handling compared to discrete components
Low Profile; Can be used in PCMCIA cards
