GS8A032490CAT

GS8A032490CAT Description

The GS8A032490CAT from TT Electronics/IRC is a high-precision 8-resistor isolated network in a 16-pin narrow SOIC package, designed for demanding applications requiring tight tolerance and thermal stability. Built with thin-film technology on a ceramic substrate, it delivers exceptional performance with a ±0.25% absolute tolerance and ±0.05% ratio tolerance, ensuring minimal deviation in matched resistance values. The network operates over a wide temperature range (70°C to 125°C) with a low ±25ppm/°C temperature coefficient, making it ideal for precision analog and signal conditioning circuits.

GS8A032490CAT Features

• High Precision: 249Ω resistance with ±0.25% tolerance and ±25ppm/°C TCR for stable performance.
• Robust Construction: Ceramic SOIC package ensures durability and thermal reliability.
• Isolated Design: Eight independent resistors (non-bussed) for flexible circuit integration.
• Surface-Mount Ready: Gull-wing termination and 1.27mm pitch for easy PCB assembly.
• Power Handling: 0.1W per resistor (0.8W total) and 100V max rating for versatile use.
• Compact Dimensions: 9.91mm × 5.99mm × 1.45mm with tight tolerances (±0.1mm height/length).
