GS4A029311GGT

GS4A029311GGT Description

The GS4A029311GGT from TT Electronics/IRC is a high-precision 4-resistor network designed for isolated circuit applications (ISOL). Housed in a ceramic SOIC-8 package, it features thin-film technology for stable performance, offering a 9.31KΩ resistance per element with a tight ±2% absolute tolerance and ±2% ratio tolerance. The device operates across a wide temperature range (-70°C to +125°C) with a low ±50ppm/°C temperature coefficient, ensuring minimal drift in demanding environments. Its 100V maximum voltage rating and 0.1W power rating per resistor (0.4W total) make it suitable for precision analog and digital circuits. The gull-wing termination and surface-mount design (4.9mm x 5.99mm footprint) facilitate easy PCB integration.
