GS4B021781GDT Description

The GS4B021781GDT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC (SOIC-C Series) device features 7 bussed resistors with a 1.78KΩ resistance value and a tight ±2% absolute tolerance, ensuring consistent performance in demanding circuits. Its thin-film technology and ±50ppm/°C temperature coefficient provide excellent stability across a wide operating temperature range of -70°C to +125°C. The 0.05W (1/20) power rating per resistor and 0.4W total power rating make it suitable for low-power, high-density designs. Encased in a rectangular ceramic package, it offers superior thermal and mechanical reliability compared to polymer-based alternatives.
