GS8A038662BBT Description

The GS8A038662BBT from TT Electronics/IRC is a high-precision 8-resistor network designed for demanding isolation and signal conditioning applications. Housed in a 16-pin narrow SOIC ceramic package, it features isolated thin-film resistors with a tight tolerance of ±0.1% and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range (70°C to 125°C). With a resistance value of 86.6kΩ per element and a derated power rating of 0.1W per resistor (0.8W total), this network is optimized for precision analog circuits. Its 100V maximum voltage rating and gull-wing termination make it suitable for surface-mount assembly in space-constrained designs.

GS8A038662BBT Features

• High Precision: ±0.1% absolute tolerance and ±0.1% ratio tolerance for matched performance.
• Stable Performance: Low ±25ppm/°C TCR ensures minimal drift under thermal stress.
• Robust Construction: Ceramic SOIC package (9.91mm × 5.99mm × 1.45mm) with ±0.1mm dimensional tolerances.
• Isolated Design: Independent resistors (no common node) for flexible circuit integration.
• Wide Operating Range: Rated for 125°C maximum temperature and derated up to 70°C.
• Surface-Mount Ready: Gull-wing leads with 1.27mm pitch for automated PCB assembly.

GS8A038662BBT Applications

This resistor network excels in precision instrumentation, medical devices, and industrial control systems where signal isolation and stability are critical. Key use cases include:
