GS4A0146R4GGT Description

The GS4A0146R4GGT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a resistance value of 46.4Ω and a tight ±2% absolute tolerance (with ±2% ratio tolerance). The device operates over a wide temperature range of 70°C to 125°C, with a ±100ppm/°C temperature coefficient, ensuring minimal drift in harsh environments. Its SOIC-C series construction offers superior reliability, with a 0.1W (1/10W) power rating per resistor (0.4W total) and a 100V maximum voltage rating. The ceramic case and gull-wing termination provide robust mechanical and electrical performance, making it ideal for surface-mount applications.
