GS4B034702CT Description

The GS4B034702CT 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 47KΩ resistance per element with an exceptional ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. Its 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for precision analog and digital circuits. The gull-wing termination and 1.27mm terminal pitch facilitate reliable PCB mounting, while the ceramic case enhances thermal performance and durability.

GS4B034702CT Features

• High Precision: ±0.25% absolute tolerance and ±25ppm/°C TCR for stable performance.
• Robust Construction: Ceramic case with SOIC package (4.9mm × 5.99mm × 1.45mm) ensures thermal and mechanical reliability.
• Bussed Design: 7 resistors with a common bus (8-pin configuration) simplify circuit layout.
• Wide Temperature Range: Operates from -70°C to +125°C with derated power up to 125°C.
• Surface-Mount Ready: Gull-wing leads and 1.27mm pitch for easy assembly.
• Low Power Dissipation: 0.05W per resistor (0.4W total) balances performance and energy efficiency.

GS4B034702CT Applications

This resistor network is ideal for:

• Precision voltage dividers in measurement equipment.
• Signal conditioning in industrial control systems.
• Analog-to-digital converter (ADC) reference circuits.
• Bus termination in communication interfaces.
• Automotive and aerospace electronics (though not PPAP/automotive-certified, its ceramic construction suits harsh environments).
