GS4B031211JAT Description

The GS4B031211JAT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. It features 7 resistors in a 1.21KΩ configuration with a 5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Encased in a ceramic SOIC package, this 8-pin gull-wing SMD component offers a 0.4W total power rating (0.05W per resistor) and a maximum voltage rating of 100V. Its compact dimensions (4.9mm x 5.99mm x 1.45mm) and surface-mount design make it ideal for space-constrained PCB layouts.

GS4B031211JAT Features

• Thin-film technology: Delivers superior accuracy and stability compared to thick-film alternatives.
• Ceramic case: Enhances thermal management and durability in harsh environments.
• BUS circuit designator: Optimized for bus termination and signal conditioning applications.
• Low TCR (±25ppm/°C): Minimizes resistance drift under temperature fluctuations.
• Gull-wing termination: Ensures reliable solder joints for automated assembly processes.
• Non-automotive grade: Suitable for industrial, telecom, and instrumentation use where PPAP compliance is not required.
