GS4A024121GT

GS4A024121GT Description

The GS4A024121GT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 4-resistor isolated network is housed in an 8-pin narrow SOIC package, featuring 4.12KΩ resistance per element with a tight ±2% tolerance and a low ±50ppm/°C temperature coefficient. Its thin-film technology ensures excellent stability, while the ceramic case style enhances thermal dissipation and durability. Rated for 0.1W (1/10W) per resistor (0.4W total) and 100V maximum voltage, it operates reliably across a 70°C to 125°C derated power range, with a 125°C maximum operating temperature. The gull-wing termination and surface-mount design facilitate automated PCB assembly.
