THICK FILM CHIP
RESISTOR ARRAYS
* Low cost
* High density packaging
* Leadless surface mount construction
* Tape & reel packaging
* Solder coated nickel barrier pads
* Isolated and bussed circuits
* Convex or Concave Termination Options
Chip Array Product Benefits
* 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
* Perfect solution for DRAM series termination or Pull up/down signal bias.
