GS4A031203BBT Description

The GS4A031203BBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring tight tolerance and stability. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a 120KΩ resistance and an absolute tolerance of ±0.1%. The device operates over a wide temperature range (70°C to 125°C) with a low temperature coefficient of ±25ppm/°C, ensuring minimal resistance drift. Its 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for precision analog and digital circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical reliability.

GS4A031203BBT Features

• High Precision: ±0.1% absolute tolerance and ±0.1% ratio tolerance for critical signal conditioning.
• Stable Performance: Low TCR (±25ppm/°C) ensures consistency across temperature fluctuations.
• Robust Construction: Ceramic SOIC package (4.9mm x 5.99mm x 1.45mm) with ±0.1mm length/height tolerances.
• Isolated Resistors: Four independent 120KΩ resistors (non-bussed) for flexible circuit design.
• Surface-Mount Ready: Gull-wing terminals with 1.27mm pitch for automated assembly.
• Wide Operating Range: Derated power up to 125°C, ideal for industrial environments.
