GS8A031781CT Description

The GS8A031781CT by 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 stability. Built with thin-film technology on a ceramic substrate, it delivers exceptional performance with a ±0.25% absolute tolerance and a low ±25ppm/°C temperature coefficient. The 1.78KΩ resistors are arranged in an isolated (ISOL) configuration, ensuring independent operation for each element. With a 0.1W power rating per resistor (0.8W total) and a 100V maximum voltage rating, this network operates reliably across a wide temperature range of -70°C to +125°C. Its surface-mount gull-wing termination and SOIC package (9.91mm x 5.99mm x 1.45mm) make it suitable for automated assembly.

GS8A031781CT Features

• High Precision: ±0.25% tolerance and ±25ppm/°C TCR ensure minimal drift in critical circuits.
• Robust Construction: Ceramic case and thin-film technology provide durability and long-term stability.
• Isolated Design: Independent resistors (ISOL) eliminate crosstalk, ideal for signal isolation.
• Wide Operating Range: Derated power up to 125°C, suitable for harsh environments.
• Compact & Reliable: 16-pin SOIC with tight dimensional tolerances (±0.1mm length/height).
