GS4B029102GGT

GS4B029102GGT Description

The GS4B029102GGT from TT Electronics/IRC is a high-performance 7-resistor bussed network designed for precision applications in demanding environments. Housed in an 8-pin narrow SOIC (SOIC-C) ceramic package, it features a 91kΩ resistance value with a tight ±2% absolute tolerance and ±2% ratio tolerance, ensuring consistent performance across all resistors. Its thin-film technology delivers excellent stability with a low ±50ppm/°C temperature coefficient, making it ideal for temperature-sensitive circuits. Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, this network operates reliably across a wide temperature range of -70°C to +125°C. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its compact dimensions (4.9mm x 5.99mm x 1.45mm) suit space-constrained layouts.

GS4B029102GGT Features

• Ceramic case (SOIC package) for superior thermal and mechanical stability.
• Bussed (BUS) circuit design simplifies routing in voltage-divider or pull-up/down applications.
• Low TCR (±50ppm/°C) ensures minimal resistance drift under thermal stress.
• High power rating (0.4W total) with derating up to 125°C.
• Precision tolerances (±2% absolute/ratio) for matched performance in differential circuits.
