GS4A031182GAT

GS4A031182GAT Description

The GS4A031182GAT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a resistance value of 11.8 kΩ and a tight absolute tolerance of ±2%. The device operates over a wide temperature range of 70°C to 125°C with a derated power rating, ensuring reliability in demanding environments. Its ±25 ppm/°C temperature coefficient and ±0.05% ratio tolerance make it ideal for circuits requiring stable, matched resistances. The SOIC-C series construction offers robust surface-mount compatibility, with gull-wing terminations for secure PCB attachment.

GS4A031182GAT Features

• Isolated Circuit Design: Four independent resistors (ISOL configuration) for flexible circuit integration.
• High Precision: Thin-film technology ensures low TCR (±25 ppm/°C) and tight ratio tolerance (±0.05%).
• Robust Packaging: Ceramic SOIC case (4.9 × 5.99 × 1.45 mm) with ±0.1 mm dimensional tolerances for consistent mounting.
• Power Handling: 0.1 W per resistor (0.4 W total) at 125°C, with a 100 V maximum voltage rating.
• Automated Assembly Friendly: Gull-wing termination and 1.27 mm pitch simplify pick-and-place processes.
• Non-Automotive: Suitable for industrial, telecom, and instrumentation applications where PPAP compliance is not required.
