GS4B012870GGT Description

The GS4B012870GGT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for precision applications, it features a 287Ω resistance value with a tight ±2% absolute tolerance and ±2% ratio tolerance, ensuring consistent performance in matched-resistor circuits. Its thin-film technology delivers excellent stability with a low ±100ppm/°C temperature coefficient, making it suitable for environments with fluctuating thermal conditions. The device operates within a wide temperature range of -70°C to +125°C, with a derated power capability up to 125°C, and offers a maximum voltage rating of 100V. Encased in a robust rectangular ceramic package, it provides superior thermal and mechanical reliability compared to polymer-based alternatives.
