742C163681JPTR

742C163681JPTR Description

The 742C163681JPTR from CTS Resistor Products (a division of CTS Corporation) is an 8-resistor network array designed for high-density surface-mount applications. This obsolete but REACH-unaffected component features a compact 2506 concave long-side terminal package with dimensions of 0.252" x 0.063" (6.40mm x 1.60mm) and a low-profile height of 0.028" (0.70mm), making it suitable for space-constrained PCB designs. Each resistor in the array offers a 680Ω resistance with a ±5% tolerance and a ±200ppm/°C temperature coefficient, ensuring stable performance across varying thermal conditions. The isolated circuit configuration allows independent resistor operation, while the 63mW power rating per element supports moderate power dissipation. Packaged in Tape & Reel (TR) for automated assembly, this RoHS3-compliant network is ideal for legacy or specialized designs requiring reliable resistance matching.

742C163681JPTR Features

• High-Density Integration: 8 isolated resistors in a miniature 2506 concave package optimize board space.
• Stable Performance: ±200ppm/°C temperature coefficient ensures minimal resistance drift under thermal stress.
