GS4B034991GT

GS4B034991GT Description

The GS4B034991GT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package, designed for demanding surface-mount applications. This thin-film resistor network offers a 4.99KΩ resistance per element with a tight ±2% absolute tolerance and an ultra-stable ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide operating temperature range of 70°C to 125°C. With a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it combines robustness with precision. The gull-wing termination and 1.27mm terminal pitch facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical stability.

GS4B034991GT Features

• Bussed Network Design: 7 resistors connected in a single bus configuration (Circuit Designator: BUS), simplifying circuit layouts.
• High Stability: Thin-film technology and ±25ppm/°C TCR ensure minimal resistance drift under thermal stress.
• Compact & Robust: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) SOIC package with ±0.1mm dimensional tolerances for precise placement.
• Automated Assembly Friendly: Gull-wing leads and standardized SOIC footprint compatible with pick-and-place systems.
• Wide Voltage Range: Supports up to 100V, suitable for industrial and instrumentation applications.
• Non-Automotive Grade: Ideal for commercial and industrial electronics where PPAP compliance is not required.
