GS4B011150GDT Description

The GS4B011150GDT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package, designed for precision applications. It features a 115Ω resistance per element with a tight ±2% absolute tolerance and ±0.5% ratio tolerance, ensuring consistent performance in differential signaling and voltage division circuits. The thin-film technology delivers excellent stability, with a ±100ppm/°C temperature coefficient, making it suitable for environments with fluctuating thermal conditions. Rated for 0.05W (1/20W) per resistor and 0.4W total power dissipation, it operates reliably across a 70°C to 125°C derated range, with a maximum voltage rating of 100V. Its gull-wing termination and surface-mount design facilitate easy PCB integration.

GS4B011150GDT Features

• Ceramic substrate for enhanced thermal and mechanical robustness.
• Bussed (BUS) topology simplifies circuit design in multi-resistor applications.
• Low TCR (±100ppm/°C) ensures minimal resistance drift under temperature variations.
• Compact SOIC package (4.9mm × 5.99mm × 1.45mm) saves board space.
• High power density (0.4W total) for its size, outperforming similar networks.
• Non-automotive (PPAP No) but suitable for industrial and telecom applications.
• Non-RoHS compliance may be preferred for legacy or high-reliability systems.

GS4B011150GDT Applications

Ideal for precision analog circuits, voltage dividers, and impedance matching networks, this resistor array excels in:

• Test & measurement equipment requiring stable resistance ratios.
• Industrial control systems where temperature stability is critical.
• Telecommunication infrastructure for signal conditioning.
• Legacy military/aerospace electronics due to its ceramic construction and non-RoHS status.
