GS4B012551GGT

GS4B012551GGT Description

The GS4B012551GGT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable thin-film resistance. It features a 2.55KΩ resistance per element with a tight ±2% absolute tolerance and ±2% ratio tolerance, ensuring consistent performance in matched circuits. The ceramic-based construction and SOIC-C series design offer superior thermal stability, with a ±100ppm/°C temperature coefficient and operation up to 125°C. Its 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for moderate-power applications. The gull-wing termination and 1.27mm terminal pitch facilitate reliable surface-mount assembly.

GS4B012551GGT Features

• Bussed Network: 7 resistors tied to a common bus, simplifying circuit design for voltage division or pull-up/down applications.
• Thin-Film Technology: Delivers low noise and high stability compared to thick-film alternatives.
• Ceramic Case: Enhances thermal dissipation and mechanical robustness in harsh environments.
• Precision Tolerances: ±2% absolute and ratio tolerance for critical analog/digital signal conditioning.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ideal for industrial and automotive (non-AECQ) systems.
• Compact SOIC Package: 4.9mm × 5.99mm × 1.45mm dimensions with ±0.1mm length/height tolerances for space-constrained PCBs.

GS4B012551GGT Applications
