GS4A0229R4JGT Description

The GS4A0229R4JGT from TT Electronics/IRC is a high-performance 4-resistor isolated network designed for precision applications in demanding environments. Housed in an 8-pin narrow SOIC (SOIC-C) ceramic package, it features thin-film technology with a resistance value of 29.4Ω and a tight ±5% absolute tolerance (with ±2% ratio tolerance). The device operates over a wide temperature range of -70°C to +125°C, ensuring reliability in thermally challenging conditions. With a power rating of 0.1W per resistor (0.4W total) and a maximum voltage rating of 100V, it is engineered for stability and efficiency. The ±50ppm/°C temperature coefficient minimizes resistance drift, making it ideal for precision circuits.
