74x Series Chip Resistor Arrays
The 74x Series Chip Arrays are single-packaged devices featuring an array of homogeneous resistor elements, designed for convenience and cost savings in electronic layouts. Utilizing low-cost thick film technology with leadless surface mount construction, these arrays offer concave or convex terminations and solder-coated nickel barrier pads. Available in isolated and bussed circuit configurations, they provide improved TCR tracking compared to discrete resistors and reduce component count for fewer placements. Packaged in tape and reel, they are suitable for high-density, low-profile designs.
