GS8A031543FAT

GS8A031543FAT Description

The GS8A031543FAT from TT Electronics/IRC is a high-precision 8-resistor network in a 16-pin narrow SOIC package, designed for isolated (ISOL) circuit applications. Built with ceramic substrate and thin-film technology, it delivers superior stability with a ±25ppm/°C temperature coefficient and ±1% absolute tolerance. Each resistor offers 154KΩ resistance at 0.1W (1/10W) power rating per element, totaling 0.8W for the network. The SOIC-C series construction ensures reliability in 70°C to 125°C environments, with a 100V maximum voltage rating. Its gull-wing termination and 1.27mm pitch facilitate easy surface-mount assembly.

GS8A031543FAT Features

• Isolated Resistor Network: 8 independent resistors for flexible circuit design.
• High Precision: ±1% tolerance and ±0.05% ratio tolerance for critical analog/digital signal conditioning.
• Stable Performance: ±25ppm/°C TCR and ceramic case ensure minimal drift under thermal stress.
• Robust Construction: Narrow SOIC (9.91mm x 5.99mm x 1.45mm) with ±0.1mm dimensional tolerances for consistent PCB fit.
• Wide Operating Range: Rated for 125°C max temperature, derated up to 125°C.
• Non-Automotive: Suitable for industrial, telecom, and instrumentation applications.

GS8A031543FAT Applications
