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

Series 741, 742, 743, 744, 745, 746

Technical

* 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.
