GS4A031801DBT Description

The GS4A031801DBT from TT Electronics/IRC is a high-precision 4-resistor network in an 8-pin narrow SOIC package, designed for demanding isolation and signal conditioning applications. Built with thin-film technology on a ceramic substrate, it delivers exceptional stability with a ±25ppm/°C temperature coefficient and ±0.5% absolute tolerance. The 1.8KΩ resistors are isolated (ISOL), ensuring minimal crosstalk, while the 0.1W power rating per resistor (0.4W total) supports reliable operation up to 125°C. The SOIC-C series package features gull-wing terminations for robust surface-mount assembly, with tight dimensional tolerances (±0.1mm height/length, ±0.2mm depth).

GS4A031801DBT Features

• Precision Performance: ±0.5% tolerance and ±0.1% ratio tolerance for critical analog circuits.
• High-Temperature Stability: Operates from 70°C to 125°C with derated power, ideal for harsh environments.
• Low TCR: ±25ppm/°C ensures minimal resistance drift.
• Isolated Design: Reduces interference in multi-channel systems.
• Robust Construction: Ceramic case and 100V max voltage rating enhance durability.
• Compact Footprint: 4.9mm × 5.99mm × 1.45mm (L×D×H) saves PCB space.
