GS4A021243CT Description

The GS4A021243CT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC package, this 4-resistor isolated network features a 124KΩ resistance value with an ultra-tight ±0.25% tolerance and a low ±50ppm/°C temperature coefficient. Its thin-film technology ensures stable performance across a wide temperature range (70°C to 125°C) while maintaining a 0.1W power rating per resistor (0.4W total). The SOIC ceramic case provides excellent thermal and mechanical stability, making it suitable for high-reliability environments. With a 100V maximum voltage rating and gull-wing termination, it is optimized for surface-mount assembly in compact PCB designs.
